On 25 March 1941, Prince Paul of Yugoslavia, an ethnic Serb, signed Yugoslavia's alliance with the Axis Powers under the Tripartite Pact. The decision was unpopular in many parts of the country, and massive demonstrations took place in the Yugoslav capital, Belgrade. Prince Paul was overthrown, and a new government under Peter II and Dušan Simović took power. The new government withdrew its support for the Axis but did not repudiate the Tripartite Pact. Nevertheless, Axis forces, led by Nazi Germany, invaded Yugoslavia on April 6, 1941.
