Start of the 'Infamous Decade'
The 1930 coup d'état, also known as the September Revolution by its supporters, involved the overthrow of the Argentine government of Hipólito Yrigoyen by forces loyal to General José Félix Uriburu. The coup took place on 6 September 1930 when Uriburu led a small detachment of troops into the capital, experiencing no substantial opposition and taking control of the Casa Rosada. Large crowds formed in Buenos Aires in support of the coup. Uriburu's forces took control of the capital and arrested Radical Civic Union supporters. There were no casualties in the coup. Future Argentinean President Juan Perón took part in the coup on the side of Uriburu.
Background.
In the lead up to the coup, the Yrigoyen government brought more power into the presidency and away from the legislature by sending large groups of his followers into the provinces, cutting off the Conservative support base. By 1922, the democratic legitimacy of the government was in question and support for Argentine democracy had begun to waver.
Uriburu's coup was supported by the "Nacionalistas". Uriburu himself was part of the "Nacionalista" Argentine Patriotic League and had the support of a number of "Nacionalista" military officers. "Nacionalista" plans for such a coup had been developing since 1927, when politician Juan Carulla approached Uriburu for support of a coup to entrench an Argentine version of Fascist Italy's Charter of Labour. With the onset of the Great Depression in 1929 that impacted Argentina, Yrigoyen lost political support as he retrenched government services which resulted in acceleration of unemployment.
Yrigoyen's consolidation of powers drew condemnation even from politically aligned parties, and the opposition parties formally protested his rule on 9 August, 1930. On the 20th, this statement was joined by a similar protest issued by the opposing faction within the Radical Civic Union.
Aftermath.
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. Uriburu proposed that Argentina be reorganized along corporatist and fascist lines. The coup marked the start of the Infamous Decade, a 13 year period during which the military ruled Argentina through repression, political corruption and electoral fraud.
