Thinking with places

July 6, 2025

“A farmer has to cut down trees to create space for his farmstead and fields. Yet once the farm is established it becomes an ordered world of meaning—a place—and beyond it is the forest and space.” — Yi-Fu Tuan

Thinking itself is place-making: the act of converting undifferentiated possibility into navigable meaning.

A place comes into being the moment we interrupt undifferentiated space. Place-making is fundamentally an act of interruption. Space is thought of as possibility but is unavailable without the signposts of place. When a place is created we impose a way of looking, being, and acting on the space of choice. The place you pick to navigate your space defines the identity you will inhabit during your quest. Every tool is a micro-place: it frames what can be thought and forecloses alternative moves. They enforce the kind of thoughts that can be had, the type of exploration that can be done, and configures space in an opinionated way.

Picking a tool commits us to a world view. Consider the space of ‘good TV shows’. Family, friends and culture have made the choice of what good means. When Netflix suggests shows it uses your watching history as a probe to create place so that every individual is always watching ‘good’ shows. The pure possibility space of the search bar is disrupted by the suggestions provided.

Like algorithmic curation, Socratic dialogue also interrupts space, it is interrogation as cartography. Socratic thinking is also an act of interruption and making concrete what was nebulous. It’s asking us to specify which show, if we claim to love TV. Socratic thinking (henceforth referred to as just thinking) starts by probing that which does not need questioning, the answers that are obvious the ones that everyone knows. This may seem foreign at first glance but we do this all the time, say we make a list of our favorite TV shows, someone always says you are missing this or that show and that this list is completely wrong. This kind of disagreement leads to the shared quest of answering the question, ‘What is it to be entertained?’.

Thinking pursues knowledge through the act of stabilizing answers to such questions by creating places in those unexamined areas. Discussion allows us to map. There is usually no well defined answer for such questions, if there were, they would simply be problems that we could solve with a google search. The quest stops when the parties involved are satisfied that they have arrived at an answer. Thinking is the act of place-making by taking something that was ungraspable and tying it down with knowledge. Place is, after all, an “ordered world of meaning” and we can use these places to create home bases from which to explore.

Even without other people simply engaging with the reality of the universe is sufficient for thought. Places are stable systems which provide a surface on which your thoughts and hypothesis can be tested. Even if there is no other person around and you’re simply engaged with looking at the world can uncover a new truth tied down by knowledge.

Thinking is the process of updating beliefs based on the mini places that make up the space that you’re interrogating. Each place is a noisy pointer to the underlying truth, and each updating of belief allows you to get closer to the knowledge you seek.

Chatbots, Bats & Broken Oracles

July 5, 2025

I had the strangest conversation with my son today. There used to be a time when computers never made a mistake. It was always the user that was in error. The computer did exactly what you asked it to do. If something went wrong it was you, the user, that didn’t know what you wanted. After decades of that being etched in today I found myself telling him that computers make mistakes, you have to check if the computer has done the right thing and that is actually ok. A computer that hallucinates also provides a surface for exploration and seeking answers to questions.

In her book, Open Socrates, Agnes Callard draws our attention to the differences between problems and questions. I’ll get to those in a bit, but the fundamental realization I had was that until recently all we could use computers (CPUs, spreadsheets, internet) for was solving problems. This started all the way back with Alan Turing when he designed the Turing test. He turned the question of what is it to think into the problem of how do you detect thought. As Callard mentions, LLMs smash the Turing test but we still can’t quite accept the result as proof of thinking. What is thinking then? What are problems? What are questions? How do we answer questions?

Problems are barriers that stand in your way when you are trying to do something. You want to train a deep learning algorithm to write poetry, how to get training data is a problem. You want something soothing for lunch, getting the recipe for congee is the problem. The critical point here is that as soon as you have the solution, the data, the recipe, the problem disappears. This is the role of technology.

When we work with computers to solve problems we are essentially handing off the task to the computer without caring that the computer wants to or even can want to write poetry or have a nice lunch. So we ask the LLM to write code, we command google to give us a congee recipe. Problems don’t need a shared purpose, only methods to solve them to our satisfaction. Being perpetually dissatisfied with existing answers is the stance of science.

Science and technology are thus tools to move towards dealing with questions. Unlike problems which dissolve when you solve them, questions give you a new understanding of the world. The thing with asking questions is that there is no established way, at least in your current state, to solve them. Thus asking a question is the first step of starting a quest. In terms of science the quest is better understanding of something and you use technology along the way to dissolve problems that stand in your way.

AI lets us explore questions with, rather than merely through, computers. Granted that most common use of AI is still to solve problems, LLMs and their ability to do back and forth chat in natural language does provide the affordance to ask questions. Especially, the kind that seem to come pre-answered because we are operating from a posture where not having an answer would dissolve the posture altogether.

The Socratic Co-pilot #

As a scientist, the question “what is it to be a good scientist?” comes pre answered for me. Until I am asked this question I have not really thought about it but rush to provide answers. Scientists conduct experiments carefully, they know how to do use statistics, they publish papers and so on. However, this still does not answer what it is to be a good scientist. Playing this out with an AI, I assert “rigorous statistics,” the AI counters with an anecdote on John Snow’s cholera map and I’m forced to pivot. None of these by themselves answers the root question, but it allows generation of some problems which can be answered or agreed on. This is knowledge.

Knowledge draws boundaries, or as I have explored earlier, creates places around the space that you wish to explore. In the space of “being a good scientist”, we can agree that the use the scientific method is an important factor. Depending on who you are, this could be the end of quest.

Even if no methodology exists for a given problem, simply approaching any problem with an inquisitive posture creates a method, however crude. In his book What Is It Like to Be a Bat? Thomas Nagel tackles an impossible to solve problem but a great question, through the process of a thought experiment. If I were to undertake this, I may try to click in a dark room, hang upside down. Okay, maybe not the last bit, but only maybe. Even this crude approach has now put me in the zone to answer the problem. Importantly my flapping about has created surface area where others can criticize, as Nagel was. Perhaps future brain-computer-interface chips will actually enable us to be a bat. However, lacking such technology, this is better than nothing as long as you are interested in inquiring about the bat-ness.

This kind of inquiry, this pursuit of answering questions is thinking. Specifically, as Callard puts it, thinking is “a social quest for better answers to the sorts of questions that show up for us already answered”. Breaking that down further it’s social because it’s done with a partner who disagrees with you because they have their own views about the question. It’s a quest because the both parties are seeking knowledge. The last bit about questions being already answered is worth exploring a bit.

Why bother answering questions you already have answers to? This is trivial to refute when you know nothing about a subject. For example let’s say you knew nothing about gravity and your answer to why you are stuck to the earth cause we are beings of the soil and to the soil we must go, the soil always calls us. If that is the worldview then you already have the answer. The only way to arrive at a better answer, gravity, is to have someone question you on the matter. Refuting specific points based on their own points of view. This may come in the form of a conversation, a textbook, a speech etc. I suspect this social role may soon be played by AI.

Obviously hallucinations themselves aren’t great but the ability to hallucinate is. In the coming years I expect AI will gain significant amounts of knowledge access not just in the form of training but in the form of reference databases containing data broadly accepted as knowledge. In the process we will probably have to undergo significant social pains to agree on what Established Knowledge constitutes. Such a system will enable LLMs to play the role of Socrates and help the user avoid falsehoods by questioning the beliefs held by the user.

Until now computers couldn’t play this role because there wasn’t enough “humanness” involved. In the bat example, a bat cannot serve as Socrates or as the interlocutor to a human partner because there isn’t a shared world view. LLMs, trained on human generated knowledge would have enough in common to provide a normative mirror. The AI comes with the added benefit of having both infinite patience and no internal urge to be right. This would allow the quest to provide an answer that is satisfactory to the user searching at every level of understanding. LLMs can be useful even before they gain the ability to access established knowledge. Simply by providing a surface on which to hang questions the user can become adept at the art of inquiry.

So the next time you have a chat with your pet AI understand that it starts as a session of pure space. Each word we put in ties down the AI to specific vantage points to help us explore. Go ahead—pick a question you think you’ve already answered and let the machine argue with you.

Reflection on the VGR bookclub

June 28, 2025

This bookclub is the most fun thing I’ve done in a decade… this includes starting, expanding, and leaving a startup ;)

The last fun thing was post-PhD rapid exploration of applying AI for bio, which laid the foundation for where I am now.

The book club feels like a philosophical anchoring to understand complexities of the world and, as I turn 40, my place in it.

Financial Instruments and the Ottoman Empire’s Decline (16th–19th Centuries): A Comparative Analysis

June 20, 2025

This essay was explored with ChatGPT o3 as a curiosity while reading Islamic Gunpowder Empires by Douglas E. Streusand as part of the Contraptions Book Club

Introduction #

The decline of the Ottoman Empire from the reign of Süleyman the Magnificent (1520–1566) through the 1800s was closely intertwined with its financial system. A combination of internal fiscal instruments – such as the timar land-tenure system, tax farming (iltizam), coinage debasements, and halting reform efforts – and external financial dependencies – including capitulatory trade agreements, foreign loans, and reliance on European capital – weakened the empire’s economic foundations. This report examines how these financial tools contributed to Ottoman decline, and compares the Ottoman fiscal system with contemporaneous innovations in Venice, the Dutch Republic, England, and the Habsburg Empire. By analyzing public debt management, state banking institutions, military finance, and credit markets, we highlight how European states developed resilient “fiscal-military” systems that gave them economic and military leverage over the ailing Ottoman state. The analysis is supported by historical and academic sources, and a comparative table summarizes key differences.

Ottoman Internal Financial Instruments and Fiscal Challenges (16th–18th Centuries) #

The Timar System and the Rise of Tax Farming #

Under Süleyman I, the Ottoman Empire’s finances appeared robust. A pillar of the classical system was the timar: land grants to cavalry officers (sipahis) who collected taxes in return for military service. This decentralized feudal revenue system initially provided a steady supply of troops at low direct cost to the central treasury. However, by the late 16th century, signs of strain emerged. As the empire’s territorial expansion stalled and inflation eroded fixed revenues, the timar system began to break down. Many timar lands were seized by powerful elites and effectively converted into private estates, depriving the state of both manpower and revenue that these lands once provided.

To raise immediate cash, the government increasingly turned to tax farming (iltizam). Instead of collecting taxes directly, the treasury auctioned the right to collect provincial taxes to the highest bidder, who paid the state an upfront sum and then extracted revenues from the populace. While this provided short-term infusions of money, it incentivized farmers to maximize extraction over short tenures rather than sustainably manage resources. Observers noted that holders of timars and tax farms began to “exploit as rapidly as possible, rather than as long-term holdings”, often abusing taxpayers and neglecting future productivity. In the late 17th century, the Ottoman state attempted a reform by instituting life-term tax farms (malikâne) to encourage longer-term investment in tax sources. Yet, corruption frequently allowed influential holders to secure hereditary control or turn tax farms into tax-exempt waqf endowments, “without any further obligations to the state”. This erosion of central authority over revenue reduced the funds available for the army and administration, contributing to imperial weakness.

Monetary Debasement, Inflation and Fiscal Crisis #

When taxation and timar revenues proved insufficient, the Ottomans resorted to another expedient: monetary debasement. Successive sultans debased the silver coinage (akçe and later kuruş) by reducing its precious metal content, effectively raising nominal revenue at the cost of inflation. This policy had precedent – as early as the 15th century, Sultan Mehmed II used periodic debasements to fund his campaigns – but it became especially damaging in the late 16th and 17th centuries. The influx of New World silver into Europe drove up prices (the “Price Revolution”), and the Ottoman akçe’s value plummeted in international trade. In response, the treasury sharply debased the coinage in the late 1500s, triggering rapid inflation that disrupted the economy. Contemporary accounts describe how by the 1580s–1590s, prices for basic goods soared while soldiers’ and officials’ salaries (paid in debased coin) lost purchasing power. Indeed, “the treasury…began to meet its obligations by debasing the coinage,” but “all those depending on salaries found themselves underpaid,” leading to further corruption and unrest. Unpaid or underpaid Janissaries reacted with riots and mutinies, and provincial revolts (such as the Celali rebellions) had economic hardship as a backdrop.

Throughout the 17th and 18th centuries, fiscally motivated debasements were frequent, especially in wartime. Each debasement provided a short-lived budgetary fix but undermined long-term confidence in the currency. Notably, during the centralizing reforms of Sultan Mahmud II (r. 1808–1839), the empire carried out the “largest debasement ever in Ottoman history” – the silver content of the kuruş was reduced by over 80% between 1808 and 1844. The exchange rate of the kuruş to the British pound sterling collapsed from 18:1 to roughly 110:1 in that period. This caused steep inflation and hit fixed-income groups (bureaucrats, ulema, and especially the Janissary corps) the hardest. By the 19th century, it became clear that constant debasement was unsustainable – in 1844 the Ottoman government finally overhauled the coinage, adopting a bimetallic standard and stable gold-backed Ottoman lira, to restore credibility. Yet by then, decades of inflation had eroded popular trust and fiscal stability.

Public Finances and Attempts at Reform #

Ottoman public finance in this era struggled to adapt to new realities. The empire’s traditional revenue system had been sufficient during the 16th-century expansion, but proved inadequate against rising military costs and economic change. Crucially, the Ottoman state did not develop a funded public debt system in the early modern period akin to those in Europe. Islamic law’s discouragement of interest limited formal public borrowing, and instead the treasury relied on informal loans from Galata bankers and advance payments from tax farmers. Only in the late 18th century did the Ottomans introduce a domestic debt instrument: the esham (shares in lifelong tax annuities). First issued in 1775 after a costly war with Russia, the esham allowed investors to pre-pay a sum to the treasury in exchange for a lifelong annual income from specific tax revenues. In essence, this was an Ottoman form of life annuity or bond. While the esham system marked a step towards modern public borrowing, it remained limited in scale and was structured to avoid explicit interest, thus offering less flexibility than European bonds.

Fiscal reform efforts gained urgency in the early 19th century. Selim III (r. 1789–1807) and Mahmud II attempted to recentralize tax collection and curb abuses by powerful provincial ayans (notables). After destroying the Janissary corps in 1826, Mahmud II pursued financial centralization, including abolishing most tax farms and trying to collect taxes through salaried officials. These reforms, alongside the 1840s Tanzimat reforms (which promulgated a more equitable tax system and budgets), did modestly improve state revenues. In fact, the central government’s tax revenue as a share of GDP, which had languished around an estimated 3% in the early 19th century, rose to over 10% after mid-19th century centralizing reforms. Despite this improvement, it was a belated catch-up. As one study notes, “most European states had experienced significant increases in revenues during the early modern era… while Ottoman revenues were in fact declining” in the eighteenth century. Thus, even the 19th-century Ottoman revenue gains were “the results of delayed political and fiscal centralization”. By the time the Ottomans built a modern finance system, it was under great external pressure and hampered by the empire’s accumulated weaknesses.

External Financial Dependencies and their Impact #

Capitulations: Trade Privileges and Lost Revenues #

From the 16th century onward, the Ottomans granted Capitulations – treaties giving European merchants and diplomats special privileges in Ottoman territories. Süleyman I’s agreements with France (1536) and later capitulations to other powers allowed foreign merchants low fixed customs duties (often around 3%) and extraterritorial legal rights. In the short term, these deals aimed to encourage trade and secure alliances. However, over the long term, capitulations created an unequal trading regime that undercut Ottoman finances. European merchants (and local non-Muslim intermediaries under European protection) flooded the Ottoman market with cheap imported manufactures, but Ottoman authorities were largely unable to increase tariffs beyond the low rates locked in by capitulatory treaties. By the 18th century, this meant that Ottoman craft guilds and industries, operating under strict price controls, could not compete with European goods entering “without restriction because of the Capitulations”, leading to “traditional Ottoman industry into rapid decline.”. The empire not only suffered deindustrialization but also missed out on potential tariff revenues that European states were capitalizing on. Capitulations thus constrained the Ottoman fiscal base, making the state increasingly dependent on domestic agrarian taxes (already strained by tax farming inefficiencies) while trade revenues stagnated.

Furthermore, capitulatory privileges exempted foreigners (and their local protégés) from many local taxes and even from the jurisdiction of Ottoman courts. This fostered a quasi-colonial economic environment in ports like İzmir and Alexandria. Foreign consuls often extended protection to Ottoman Christians and Jews, who in turn dominated lucrative export-import businesses at the expense of Muslim merchants. The overall effect was a drain on Ottoman financial sovereignty: the empire’s role in global commerce shifted from that of a controller (as it had been on the Silk Road before 1600) to largely a supplier of raw materials and consumer of European goods, with little ability to regulate commerce for its own treasury’s benefit.

Reliance on Foreign Loans and European Capital #

In the mid-19th century, the Ottoman Empire’s fiscal troubles pushed it into external borrowing – a new and perilous dependency. The first major foreign loan was taken in 1854, during the Crimean War, to finance military expenses. Over the next two decades, Istanbul floated dozens of loans from European creditors (primarily British and French banks), often on onerous terms. By 1875 the nominal public debt had swollen to £200 million, an immense sum for the Ottoman budget. Annual interest and amortization payments reached £12 million – consuming “more than half of the national revenue.” In other words, over 50% of Ottoman state income was absorbed just by servicing debt, a clearly unsustainable burden. In that same year (1875), facing a global financial downturn and domestic fiscal shortfalls, the Ottoman government defaulted on its debt payments, admitting it could only cover half the interest due. This financial collapse precipitated an international intervention in Ottoman finances.

Creditors from the major European powers forced the empire to accept the Ottoman Public Debt Administration (OPDA) in 1881. This institution, run largely by European appointees, took control of key Ottoman revenue streams (such as the salt tax, tobacco tax, and customs duties) to ensure debt repayment at the source. Effectively, the OPDA meant partial control of state finances by European creditors until World War I. While this arrangement restored the Ottoman government’s creditworthiness (allowing it to borrow again at lower interest rates in subsequent years), it deeply compromised Ottoman sovereignty. European financial oversight dictated budget priorities, with creditor interests often trumping the empire’s domestic needs.

Beyond sovereign debt, European capital penetrated the Ottoman economy via direct investments: railways, ports, mining concessions, and the establishment of the Ottoman Bank (1856) which was British-French controlled and served as a quasi-central bank. The Ottomans were thus integrated into European capital markets but on unequal terms – mostly as debtors and as a zone of investment for outside interests. By the late 19th century, the empire was locked in a cycle of dependency: needing foreign loans to fund reforms or military expenditure, but those very loans leading to foreign supervision and further loss of revenue autonomy. This external financial reliance was both a symptom of the Ottoman decline and a cause of its acceleration, as the empire’s inability to independently mobilize resources left it vulnerable to diplomatic and economic pressure from the Great Powers.

European Fiscal Innovations vs. the Ottoman System #

Early modern Europe witnessed a “financial revolution” in statecraft that the Ottoman Empire largely missed until it was too late. European states developed new financial instruments and institutions – from permanent public debts to central banks and sophisticated credit markets – which underpinned their rise in power. Below, we compare the Ottoman financial system to those of Venice, the Dutch Republic, England, and the Habsburg monarchy, emphasizing public debt management, banking, military finance, and credit markets. The contrast reveals how European innovations yielded greater fiscal resilience and military-economic leverage.

Public Debt and Credit Markets: Ottoman Lag vs. European Innovation #

One of the starkest differences was in public debt management. Unlike the Ottomans, who avoided long-term interest-bearing debt until the late 18th century, several European states had developed perpetual public debts centuries earlier:

Venice: Pioneered public borrowing as early as the 12th–13th centuries. The Venetian Republic’s government issued prestiti (forced loans from wealthy citizens) which evolved into transferable government bonds. By 1261 Venice had reorganized its debt into the Monte Vecchio, and set a standard interest rate of 5% on these perpetual bonds. For roughly a century the rate held steady, indicating investor confidence. A secondary market for Venetian bonds flourished by the late 1200s – nobles traded them and used them as dowry assets, with prices publicly quoted. The state even established a sinking fund to buy back bonds when prices fell, shoring up the market. These practices made Venice’s credit extremely robust for the era; historians have dubbed the prestiti the first “AAA” government bonds for their reliability. Venice thus could finance costly wars (against Genoa, the Ottomans, etc.) by floating debt rather than resorting to debasement or ruinous taxation. This early financial sophistication eluded the Ottoman Empire, which lacked a comparable credit instrument during its 16th-century heyday and long after.
Dutch Republic: During its war of independence (1568–1648) against Habsburg Spain, the Netherlands (especially the province of Holland) developed a modern system of public finance. The Dutch raised enormous sums via voluntary bonds, backed by new permanent taxes. By the mid-17th century the Dutch Republic was able to borrow at remarkably low interest rates – around 5%, dropping to 4% by the 1660s. Dutch public bonds (including annuities called losrenten and lijfrenten) were widely held by a large investor base, and the interest rates were “equal to, or lower than, the lowest interest returns available in the private sector.” In fact, the Dutch essentially introduced the concept of perpetual, interest-only national debt: the government often paid only interest and could postpone principal redemption indefinitely, allowing it to “spend according to its needs without practical limit”. This extraordinary credit capacity enabled the tiny Dutch Republic to field armies and navies in excess of what its tax revenue alone could support. By the late 17th century, Amsterdam had become the financial capital of Europe – Dutch financiers not only funded their own state but also started investing heavily in other nations’ debts. In comparison, the Ottoman Empire’s nascent attempts at internal borrowing (like the esham of 1775) were timid and expensive, and the empire had to pay much higher effective interest when it finally issued Eurobonds in the 1850s (often borrowing at 8–12% when underwriting costs are included). The absence of a deep domestic credit market left the Ottomans fiscally brittle.
England (Britain): England was a latecomer compared to Italy or the Netherlands, but by the 18th century it surpassed them through what historians call the Financial Revolution. After 1688, the English state, now constrained by Parliament, established the Bank of England (1694) and began issuing a funded National Debt. The Bank of England’s creation was pivotal: previously English monarchs had to borrow from private lenders at up to 30% interest, but with the Bank’s formation (and its initial £1.2 million loan to the government at 8%), the state’s credit vastly improved. The Bank intermediated between investors and the state, creating a liquid market for government bonds. By the mid-18th century, Britain was selling long-term bonds at 3%–5% interest, comparable to the Dutch rates, and far below the cost of capital for the Ottomans. Each major war saw Britain’s national debt mount: from about 22% of GDP in 1700 to an staggering ~155% of GDP on the eve of the Napoleonic Wars. Yet Britain never defaulted; instead it serviced the debt via regular taxation and enjoyed access to “large pools of financing a strategic advantage over its rivals.” In effect, Britain could wage war on credit, deferring the costs over decades, whereas the Ottoman Empire – lacking such credit mechanisms – often had to either curtail military operations or resort to desperate measures like debasing currency when funds ran out. The concept of marketable, liquid government debt, which Britain and the Dutch mastered, was largely absent in the Ottoman fiscal arsenal until the very end, when it came under foreign tutelage.
Habsburg Empire (Austria): The Habsburg monarchy (Austria and its Central European territories) offers a intermediate case. In the 16th–17th centuries, the Habsburgs’ finances were quite strained; they relied on a patchwork of estate contributions, high-interest loans from Italian and German bankers, and often fell into arrears or partial defaults (the Spanish Habsburgs famously went bankrupt several times in the 16th century). However, the constant Ottoman threat and wars in Europe forced Habsburg Austria to attempt fiscal reforms. By the 18th century, Maria Theresa and Joseph II introduced more centralized taxes and began to institutionalize public credit. For example, after the Seven Years’ War (1756–1763) inflicted massive costs, the Austrian treasury had to service a huge war debt that “for the remainder of Maria Theresa’s reign” dominated policy. This led to the creation of the Vienna Stadtbank and other instruments to consolidate and manage debt. The Habsburgs never achieved the low interest rates of Britain or Holland – their credit was seen as riskier – but by the early 19th century Austria had a central bank (established 1816) and an increasing tax base. Still, compared to Britain’s ~8% of GDP tax intake in the eighteenth century, Habsburg taxes were lower and its debt less sustainable, contributing to Austria’s financial crisis and default in 1811 during the Napoleonic Wars. In sum, the Habsburgs did move toward the European model of funded debt and fiscal centralization, but more slowly and with frequent setbacks. Tellingly, even this partial modernization was more than what the Ottomans managed until very late – by which time the Habsburgs (and other European states) could draw on British subsidies or international loans in their wars against the Ottomans.

State Banking and Monetary Institutions #

European advances in banking and monetary policy also contrasted with Ottoman practices:

Venice and Italy: Venice established one of the first public banks, the Banco di Rialto in 1587, followed by the Banco del Giro. These were primarily banks of deposit and transfer, created to stabilize the currency and facilitate trade payments. While not “central banks” lending to the state, they enhanced Venice’s financial infrastructure by providing a stable credit system for merchants. Italian city-states like Genoa and Florence had earlier innovations (e.g. Genoa’s Bank of St. George managed state debt). The Ottomans, by contrast, had no equivalent public banking institution in the classical period. Money changing and credit were left to private sarraf (moneylenders), often from minority communities, operating without a unified regulatory framework. This meant higher transaction costs and interest rates for the Ottoman government when it needed short-term credit.
Dutch Republic: The Amsterdam Wisselbank (Exchange Bank) founded in 1609 was a crucial institution. It was a city-owned bank that accepted deposits of coin and allowed cashless transfers, greatly simplifying trade finance. It helped keep the Dutch currency stable and became a hub for European bullion trading. Though the Wisselbank did not directly finance government debt, its sound operations underpinned Amsterdam’s role as a financial center and increased confidence in Dutch financial instruments. The Ottomans, lacking such a bank, faced chronic currency instability (periodic debasements, as discussed) and could not as effectively mobilize the wealth of their merchants for state purposes.
England: The Bank of England (est. 1694) was revolutionary because it combined central banking functions with public debt management. In return for lending to the state, the Bank was granted note-issuing powers, effectively creating a paper money backed by government debt. Over the 18th century, the Bank became the lender of last resort and war financier for Britain. It coordinated with the Treasury to manage the national debt and stabilize the financial system (for instance, during crises it intervenated to shore up confidence). The Ottoman Empire did not establish a comparable institution until the mid-19th century, and even then the Ottoman Bank (originally founded 1856, reconstituted as the Imperial Ottoman Bank in 1863) was operated by British and French interests. The Ottoman Bank issued banknotes and acted as treasury banker, but its policy was often aligned with protecting European creditors’ interests, not purely the Ottoman economy. Without an independent central bank, the Ottoman state lacked tools to conduct monetary policy or to readily raise short-term funds in emergencies – tools that Britain used to great effect.
Monetary Stability: By the 19th century, most Western European states adopted gold or bimetallic standards, ensuring stable currencies which helped attract investment and keep borrowing costs low. Britain, for example, was effectively on a gold standard by the early 19th century and enjoyed low inflation. The Ottomans only stabilized their currency with the 1844 reform (switching from the debased kuruş to a new gold lira). Before that, continuous debasements had caused such price chaos that, as noted, economic actors in the empire were well aware of “who gained and who lost” from each coinage change. The relative stability of European currencies (especially the Dutch gulden and British pound) versus the chronic Ottoman currency crises further enhanced investor trust in European financial instruments and distrust in Ottoman ones. This divergence was self-reinforcing: stable money allowed Europeans to sustain large standing armies and navies (paid in reliable currency), whereas the Ottoman armed forces were frequently restive over debased pay.

Taxation, Military Finance, and Expenditure #

Underpinning debt and banking was the ability to extract revenue. European states gradually built more effective tax systems than the Ottoman Empire:

By the 18th century, Britain and France had developed professional fiscal bureaucracies that directly collected customs, excises, and land taxes, largely eliminating tax farming. Britain’s tax revenue reached about 8–12% of GDP in the late 18th century, among the highest in Europe, funding both debt interest and a worldwide war effort. The Ottoman central government, even after reforms, collected around 3–5% of GDP in taxes until much later. This lower tax base meant fewer resources for the military. The Ottomans still relied heavily on provincial elites to raise troops and funds, whereas European monarchies could tap national wealth through centralized taxes.
Habsburg Austria lagged Britain/France but still increased its fiscal intake over time through centralized customs (the 1775 Austrian customs union) and new land taxes, despite resistance from nobles. In the critical wars of the late 17th century (Great Turkish War) and early 18th century, Austria’s ability to levy extraordinary war taxes (and receive foreign subsidies) helped it field armies that eventually outmatched the Ottomans. For example, by mobilizing the resources of the relatively prosperous Bohemian and Austrian lands, the Habsburgs could maintain a steady military pressure that the Ottomans, facing a bankrupt treasury and restive provinces, struggled to counter.
The Dutch Republic famously imposed very heavy taxes (especially excise taxes on consumption) to pay for its defense. In Holland, taxpayers bore burdens that astonished contemporaries but were accepted as the price of freedom from Spain. The Dutch could spend a high proportion of national income on their military (in the 17th century) without courting immediate fiscal collapse, thanks to a combination of high taxes and cheap debt. The Ottomans, in contrast, often had to reduce military campaigns due to lack of funds or resort to emergency measures (like seizing the properties of deceased officials or levying arbitrary surcharges) which had deleterious political effects.

In terms of military finance, the European states’ financial superiority translated directly into greater resilience and reach:

War Financing: Britain in the 18th century is a prime example – it fought numerous expensive wars (War of Spanish Succession, Seven Years’ War, Napoleonic Wars) by issuing debt and increasing taxes primarily to service that debt, not to pay war costs upfront. By one estimate, “until 1799 Britain’s eighteenth-century wars were financed by incurring debt; taxes were increased simply to pay the interest”. This model allowed Britain to mobilize resources far exceeding its annual revenue, something the Ottomans could not do. When the Ottoman Empire engaged in protracted conflicts (such as the 1768–1774 war with Russia or the 1877–78 war), it quickly exhausted available funds, leading to delayed soldier salaries, mutinies, and desperation measures (like the 1875 foreign debt moratorium). European powers could fight longer and rebound faster. For instance, after the costly Crimean War (1853–56), Britain and France absorbed the debt and moved on, whereas the Ottomans were left financially prostrate, having borrowed heavily during the war and then struggling to pay thereafter.
Resilience to Shocks: European states also proved more resilient to economic shocks from war. As Karaman and Pamuk observe, the centralized European fiscal-military states “captured increasing shares of resources as taxes” and “enjoyed greater capacity to deal with domestic and external challenges,” even being “able to shield their economies better against wars.”. In practice, this meant that even when wars caused debt spikes or temporary economic dislocation in Europe, the state’s credit and administrative structures kept the economy functioning. In the Ottoman case, wars often led to economic breakdown – for example, the 1877–78 Russo-Turkish war pushed the already indebted empire into severe default and an eventual foreign-controlled financial regime.
Military-Technical Edge: The superior financing of European powers enabled sustained investment in military technology and infrastructure – shipyards, firearms production, and later railways and telegraphs – which the Ottomans, with their strained budgets, struggled to match. The British Royal Navy, the Dutch fleet, or Austrian artillery could be expanded and modernized continuously through funded expenditures, whereas the Ottomans often fell behind in weaponry when they could not afford updates. By the 19th century, the Ottomans tried to modernize their army and navy, but had to rely on foreign credit and expertise to do so, further entangling them with European financiers.

Comparative Fiscal-Military Indicators (Ottoman Empire vs. Selected European States) #

To summarize the key differences, the table below contrasts the Ottoman financial system with those of Venice, the Dutch Republic, England (Great Britain), and the Habsburg Austrian Empire in the early modern period. It highlights how innovations in public debt, banking, and taxation gave European states a marked advantage:

Outcomes: European Leverage and Ottoman Vulnerability #

By the nineteenth century, these fiscal contrasts translated into a profound power imbalance. European states had become true “fiscal-military” states – a term describing how they could harness their economies for war through efficient taxation and credit. They not only raised more money, but did so in ways that minimized disruption. For instance, Britain’s ability to borrow allowed it to keep domestic taxes at tolerable levels during war (shifting much of the cost to future repayments), whereas the Ottomans, unable to borrow enough, often resorted to immediate heavy taxes and debasements that disrupted their economy and alienated subjects. European economies were also better “shielded” from war due to these fiscal mechanisms – production and trade could continue, even expand, while the state drew on accumulated capital. In the Ottoman case, wars and fiscal crises fed each other in a vicious cycle: military defeats cut revenue sources and forced higher extraordinary levies, which then provoked rebellions and further defeats.

Moreover, European financial leverage had a diplomatic dimension. Cash-poor regimes like the Ottomans often fell under the influence of creditor nations. This was evident in how Britain and France used loans as tools of influence in the Ottoman Empire (for example, controlling how loan funds were spent on reforms, or using debt negotiations to extract political concessions). In the era of imperialism, debt could be as potent as armies: after 1881, the Ottoman government effectively needed European creditor consent for much of its spending, limiting its freedom to act independently on the world stage. European powers could also finance proxy wars or support allies (e.g. Russia or Austria) against the Ottomans, knowing their fiscal capacity exceeded that of the sultan’s treasury. In sum, financial modernization gave European states a form of “soft power” and endurance that the Ottomans lacked.

Conclusion #

Financial instruments and institutions played a crucial role in the Ottoman Empire’s long decline. Internally, the empire’s reliance on short-term fiscal fixes – tax farming that undermined future revenues, coin debasement that fueled inflation, and only late and limited adoption of modern public debt – left the Ottoman state increasingly incapable of meeting the challenges of a changing world. Periodic reform efforts could not fully reverse the systemic weaknesses in revenue collection and monetary stability. Externally, the Ottomans gradually fell prey to the credit and capital of industrializing Europe: capitulatory trade regimes eroded the Ottoman economic base, and dependence on foreign loans led to a loss of financial sovereignty. By the late 19th century, the empire was as much a ward of European bondholders as it was an independent polity.

In contrast, contemporaneous European powers developed financial tools that gave them resilience in the face of war and crisis. Venice’s early bond market, the Dutch Republic’s low-interest loans and massive capital pools, England’s powerful combination of the Bank of England and funded debt, and even the Habsburgs’ strides in centralizing finance all enabled these states to project power more effectively. They became capable of mobilizing far greater resources per capita and sustaining conflict over longer periods than the Ottomans could. As one comparative study notes, European central states “captured increasing shares of resources as taxes” and thereby “enjoyed greater capacity to deal with…challenges” and to buffer their economies in wartime. This fiscal-military superiority translated into military victories and colonial expansions at Ottoman expense.

In summary, the story of the Ottoman Empire from Süleyman the Magnificent to the 19th century cannot be told without its financial fallibilities. The empire’s fiscal instruments, once adequate for a conquering realm, proved outdated against the new financial powers of Europe. While Ottoman reformers recognized the need to modernize (adopting new budgets, borrowing techniques, and currency reforms in the 19th century), these changes came late and under duress. The comparative evidence suggests that it was not destiny but institutions and choices that set the Ottoman Empire on a different path. In the crucible of early modern geopolitics, ducats, guilders, and pounds could be as decisive as cannons. Financial innovation became a key source of power – one that the Ottomans, for various reasons, did not fully harness in time, contributing significantly to their decline in the face of ascendant European states.
