Reparations were the payments required by the Treaty of Versailles( one of the most important peace treaties), by which Germany had to pay so as to repair all the damages of war.
Step-by-step explanation:
The Treaty of Versailles (signed in 1919) and the 1921 London Schedule of Payments required Germany to pay 132 billion gold marks (US$33 billion) in reparations to cover civilian damage caused during the war.
This treaty had significant negative impact on the German economy and the payments made it difficult for Germany, so as to take actions which would aid their economic growth.
