Karađorđe's descendants adopted the surname Karađorđević in his honour. His murder resulted in a violent, decades-long feud between his descendants and those of Obrenović, with the Serbian throne changing hands several times. The feud came to an abrupt end in June 1903, when rebellious Royal Serbian Army officers killed the Obrenović king, Alexander, and his wife, Queen Draga, thereby rendering the Obrenović line extinct. Karađorđe's grandson, Peter Karađorđević, then ascended the throne. In order to tie himself to his grandfather's legacy, Peter commissioned a bronze crown cast from a piece of Karađorđe's first cannon. In addition, the Order of Karađorđe's Star was introduced as Serbia's highest state decoration. The first feature-length film to emerge from Serbia and the Balkans, whose plot revolves around Karađorđe and his actions before, during and after the First Serbian Uprising, was released in 1911. Work soon began on the construction of the Church of Saint George, a Karađorđević dynasty mausoleum at Oplenac, near Topola. In 1913, a monument to Karađorđe was unveiled at Kalemegdan Park. During Austria-Hungary's occupation of Serbia in World War I, the monument was torn down by the Austro-Hungarian Army and destroyed. In November 1918, Peter ascended the throne of the newly established Kingdom of Serbs, Croats and Slovenes, which was later renamed Yugoslavia. Karađorđe's head was repatriated from Greece in 1923 and reunited with the rest of his body. His remains were buried in a white marble sarcophagus within the church in 1930. The Karađorđević dynasty ruled Yugoslavia until 1941, when its members were forced into exile by Germany's invasion and occupation of the country. The monarchy was abolished by Josip Broz Tito's communist government in 1945.
