Following their defeat in World War I, the Central Powers agreed to pay war reparations to the Allied Powers. Each defeated power was required to make payments in either cash or kind. Because of the financial situation in Austria, Hungary, and Turkey after the war, few to no reparations were paid and the requirements for reparations were cancelled. Bulgaria, having paid only a fraction of what was required, saw its reparation figure reduced and then cancelled. Historians have recognized the German requirement to pay reparations as the "chief battleground of the post-war era" and "the focus of the power struggle between France and Germany over whether the Versailles Treaty was to be enforced or revised."
The Treaty of Versailles (signed in 1919) and the 1921 London Schedule of Payments required the Central Powers to pay 132 billion gold marks (US$33 billion at the time which is $605 billion in 2025) in reparations to cover civilian damage caused during the war. This figure was divided into three categories of bonds: A, B, and C. Of these, Germany was required to pay towards 'A' and 'B' bonds totaling 50 billion marks (US$12.5 billion) unconditionally. The payment of the remaining 'C' bonds was interest-free and without any specific schedule for payment, instead being contingent on the Weimar Republic's eventual ability to pay, as was to be assessed at some future point by an Allied committee.
