The 6 January Dictatorship (Croatian: Šestosiječanjska diktatura, Serbian: Шестојануарска диктатура/Šestojanuarska diktatura, Slovene: Šestojanuarska diktatura) was a royal dictatorship established in the Kingdom of Serbs, Croats and Slovenes (Kingdom of Yugoslavia after 1929) by King Alexander (r. 1921–34). It lasted from January 6, 1929 when the king prorogued parliament and assumed control of the state and ended with his assassination in Marseille on October 9, 1934.
King Alexander abolished the Constitution, prorogued the National Assembly and introduced a personal dictatorship on 6 January. The next day, General Petar Živković became prime minister, heading the regime's Yugoslav Radical Peasants' Democracy. On January 11 the State Court for the Protection of the State was established in Belgrade.
On 20 April, the Croatian fascist Ustaše and Macedonian secessionist IMRO called for the independence of Croatia and Macedonia.
On 25 April Đuro Đaković, a prominent Trade unions' activist and the First secretary of the Communist Party of Yugoslavia, was murdered by Yugoslav policemen at the Yugoslav-Austrian border in present-day Slovenia, after four days of torturing and questioning in a Zagreb police station.
On 3 October, the state was renamed to the "Kingdom of Yugoslavia". The state was also divided into new administrative divisions called banovine (singular banovina).
