At the end of the Great War, the victorious allies wanted to really punish Germany for everything they had to endure in their victory. In addition to the loss of territory, the Treaty of Versailles contained a statement where Germany apologized and took all the blame for the war, and they were forced to pay some 132 billion gold marks (about $33 billion in 1919 dollars; over $500 billion today) in reparations. After a lot of refinancing (and another war sparked – in no small part – by the perceived humiliation of the reparations), the last payment was made in 2010.
In that next war, Finland wound up on the losing side due an alliance of convenience with Germany after Finland was invaded by the Soviet Union. Finland not only had to let the Soviets keep the territory they grabbed, but give them even more land and some serious cash payments. After the payments were made, a new bit of Finnish currency featured some nude figures (seen from the back) gazing at a sunset over an ocean. The joke was that it represented the Finns watching their last reparations payment going off to the Soviets.
Now there’s some serious talk – again – about reparations payments to African-Americans to atone in some fashion for slavery.
