While military leaders like Nelson get the credit, Britain's victory was largely financed by its sophisticated bond market. The ability to fund itself almost infinitely at a low 3% interest rate allowed it to sustain a long war and subsidize allies, an advantage Napoleon's France lacked.

The downfall of empires follows a predictable pattern: the discovery of debt's power leads to its abuse over successive leaderships. This creates a K-shaped economy, eventually causing either a revolution from the impoverished class or a financial default that strips the nation of power.

The Bank of England's 1694 innovation was to have lenders give money to Parliament, not the monarch. This made debt an obligation of the entire nation and its descendants, creating a stable system for financing wars.

Demonstrating extreme long-term contracting, a bond issued in 1648 by a Dutch water company to repair a dike is still active. Yale University owns the parchment bond and periodically sends a representative to the Netherlands to collect the interest payments.

A 5,000-year-old Sumerian document, the first to record a war, details how the victors calculated reparations owed by the losers using compound interest on unpaid land rent. This links a foundational financial concept directly to the dawn of recorded military conflict.

While debt existed for millennia, the Venetian innovation of making loan receipts tradable was the crucial unlock. This created a liquid marketplace and dispersed ownership, transforming a simple loan into a powerful financial tool that could flow through time and across citizens.

The creation of the Bank of England and John Law's monetary schemes were not academic exercises. They were desperate measures to solve the massive national debts accumulated by England and France from decades of war, showing how fiscal crisis is a powerful catalyst for financial innovation.

Perceived as less glamorous than stocks, the bond market is fundamentally more important. It dictates the "price of money" and has historically been the true engine of national power and economic stability, a fact often lost on the general public.

Despite its large collective economy and stable legal systems, Europe hasn't created a rival to US Treasuries because its government bond market is fragmented by country. Post-crisis austerity also discourages the large-scale borrowing needed to create a deep, unified, and liquid safe asset.
