This database maps the complete arc of human financial history — from the earliest clay tablets recording grain debts in ancient Mesopotamia, through the invention of coins, banking, joint-stock companies, and central banks, to the real-time data density of the modern era. Events are organized across twelve categories — monetary policy, geopolitical shocks, financial crises, technology disruptions, commodity events, and more — because understanding what kind of event moved a market matters as much as understanding that it moved at all. Every event from 1928 onward carries a market bias, magnitude score, and duration class, making the full timeline queryable against any price series.
