The Treaty of Saint-Germain was signed in 1919 between Austria and the Allied powers after World War 1. It required Austria to lose territory to Czechoslovakia, Yugoslavia, Italy and Romania, reducing its population from 28 million to 8 million. Austria's army was limited to 30,000 soldiers and it had to pay reparations. The treaty also forbid the union between Austria and Germany and weakened Austria to prevent its resurgence, as Italy feared increased Austrian power in the region.
