German rearmament
German rearmament (Aufrüstung, German pronunciation: [ˈaʊ̯fˌʀʏstʊŋ]) was a policy and practice of rearmament carried out by Germany from 1918 to 1939 in violation of the Treaty of Versailles, which required German disarmament after World War I to prevent it from starting another war. It began on a small, secret and informal basis shortly after the treaty was signed and was openly and massively expanded after the Nazi Party came to power in 1933.
