What was the name given to kings in Germany before 1918?
From 1871-1918 the head of state in Germany was the Emperor (Kaiser).
Germany was to pay all the war reparations for WWI (pay the cost of damage for themselves and all the Allied countries). Germany was given a payment plan that was changed several times to pay for the $33,000,000,000 dollars in damage. Germany never paid off these damages as the last payment was given in 1932, when it was guaranteed Hitler would become ruler of Germany.
