On March 25, 1941 in Vienna, Prince Paul (Pavle), Regent of the Kingdom of Yugoslavia, signed the Tripartite Pact. On March 27, the regime was overthrown by a military coup d'état with British support, and the 17 year old King Peter II of Yugoslavia seized power. General Dušan Simović became Peter's Prime Minister and the Kingdom of Yugoslavia initially tried to dissolve the Pact but later declared adherence to it. The initial agreement of the document also regarded Yugoslavia's acceptance of the free movement of German troops around the country; this was unsatisfactory to the Führer, and resulted in the Invasion of Yugoslavia. People went on streets of Belgrade and shouted "Better war then pact , better grave then slave ". There are many witnesses that claimed that there were only about 600 people on streets at that time. This action was organised by communists and Britain Intelligence Service just to satisfy the needs of Churchill to join other countries to fight with him. This led to break of Yugoslavia , Hitler declared a war to Yugoslavia and in 11 days Yugoslavia capitulated. Government fled , King fled. There was chaos. A sad moment in history. And not known to many of you.
