Prince Regent Paul declared that the kingdom of Yugoslavia would join the Tripartite Pact on 25 March 1941. Two days later, King Peter, at age 17, was proclaimed of age after a pro-British coup d'état. The initially bloodless coup was led by General Dušan Simović on 27 March 1941 in the name of Peter. As General Simović led his men toward the Royal Compound, which was surrounded by guards loyal to the Regent, Peter climbed down a drain-pipe to greet the rebels. As the Regent's guards surrendered without fighting, Simović arrived to tell Peter: "Your Majesty, I salute you as King of Yugoslavia. From this moment you will exercise your full sovereign power". The coup was very popular in Belgrade and Peter was well received by the crowds. The people who had come out in Belgrade to show their support for the coup had a very pro-Allied character, many of the protesters waving British and French flags. The crowds in Belgrade cheered Peter wildly as the 17-year-old king drove his car down the streets without his bodyguards to be greeted by his subjects. The new government that Peter swore in on 27 March 1941 was headed by General Simović and comprised members of the People's Radical Party, the Croatian Peasant Party, the Democratic Party, the Croatian Independent Democrats, the Slovene People's Party, the Yugoslav Muslim Organization, the Agrarian Party and the Yugoslav National Party. With the exception of the Yugoslav Radical Alliance and the banned Yugoslav Communist Party and the "Ustashe", all of the main political parties were represented in the new government.
