Nacionalistas 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.

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.
