1930 Argentine Coup d'état: The Fall of Yrigoyen and the Rise of Military Rule
On September 6, 1930, Argentina experienced a pivotal political shift when the government of Hipólito Yrigoyen was overthrown in a military coup. Known to its supporters as the September Revolution, this event marked the end of a constitutional era and the beginning of a period defined by instability and authoritarianism.
Led by General José Félix Uriburu, the coup saw a small detachment of troops enter Buenos Aires and seize control of the Casa Rosada (the executive mansion) without substantial opposition. The takeover was met with support from large crowds in the capital, and the forces quickly arrested supporters of the Radical Civic Union.

The Road to Revolution: Background and Causes
The collapse of the Yrigoyen administration was not an isolated event but the result of growing political and economic tension. In the years leading up to 1930, Yrigoyen consolidated power within the presidency, reducing the influence of the legislature and eroding the support base of the Conservative parties.
Political Erosion and Opposition
By 1922, the democratic legitimacy of the government began to waver. This decline was accelerated by the 1928 and 1930 congressional elections, both of which were won by opposition parties. By August 1930, formal protests against Yrigoyen's rule were issued by both opposition parties and a dissenting faction within his own Radical Civic Union.
The Influence of the Nacionalistas
The coup was heavily supported by the Nacionalistas, a nationalist movement. General Uriburu, a member of the Argentine Patriotic League, had been planning a takeover since 1927. These plans were influenced by the desire to implement a corporatist system similar to the Charter of Labour used in Fascist Italy.
Economic Collapse
The onset of the Great Depression in 1929 dealt a final blow to Yrigoyen's popularity. As the global economic crisis hit Argentina, the government was forced to retrench services, leading to a sharp increase in unemployment and a loss of public confidence.
The Aftermath and the Infamous Decade
Following the victory of the Nacionalistas, General Uriburu implemented drastic changes to the state. He banned political parties, suspended elections, and nullified the 1853 Constitution, attempting to reorganize Argentina along fascist and corporatist lines.
This event inaugurated the Infamous Decade, a 13-year period characterized by military rule, political corruption, electoral fraud, and state repression. This era set a precedent for political instability in Argentina, which continued to struggle with weak democracies and recurring military coups until the 1980s.
Notably, Juan Perón, who would later become a dominant figure in Argentine history as President, participated in the 1930 coup on the side of Uriburu.
