Did World War 1 contribute to a German economic crisis?

well one way is that war is the most expensive thing a nation can do. It costs a lot internally and then after losing they owed a lot to other countries. World War II came around and it was a repeat financial crisis after the loss. Then much later, after the fall of the Berlin Wall, East Germany had to convert to the West's currency (which was worth slightly more therefore the east lost money). Then once more Germany lost money after converting to the Euro which was worth more than the west's currency.
