How was World War I actually financed? Behind the trenches, artillery, and alliances existed a hidden financial system that made the First World War possible. This documentary reveals how gold flows, cross-border loans, central banks, and private banking houses quietly supported the biggest conflict the modern world had ever seen. From London’s gold standard system to French loans, German wartime credit, and American exports funded by European capital — this video uncovers the economic engine that powered a global war. You’ll learn how the financial networks of Barings, Rothschilds, J.P. Morgan, Deutsche Bank, and others shaped the path to conflict long before the first shot was fired. This is the true story of the money behind World War I — and how a global economic machine collapsed within days in the summer of 1914. If you want to understand war, follow the money.
