Lieutenant General José Félix Benito Uriburu y Uriburu (20 July 186829 April 1932) was the President of the Provisional Government of Argentina, ousting the successor to President Hipólito Yrigoyen by means of a military coup and declaring himself president. From 6 September 1930 to 20 February 1932, he controlled both the Executive and Legislative branches of government. As "President of the Provisional Government," he acted as the de facto Head of state of Argentina. His was the first of a series of successful coups d'état and unconstitutional governments that came to power in 1943, 1955, 1962, 1966, and 1976. Uriburu's coup was supported by the Nacionalistas, a far-right Argentine nationalist movement that around 1910 grew out of the "traditionalist" position, which was based on nostalgia for feudal economic relations and a more "organic" social order. In the aftermath of the coup, major changes to Argentinean politics and government took place, with Uriburu banning political parties, suspending elections, and suspending the 1853 Constitution.
