The Revolution of 11 September 1852 was a conflict between the Province of Buenos Aires and the government of Justo José de Urquiza after the latter triumphed over Juan Manuel de Rosas at the Battle of Caseros. A period known as "National Organization" was initiated after the Battle of Caseros. Every political faction agreed on authorizing a national Constitution. However, in opposition to the rest of the country, the ruling upper class in Buenos Aires aspired to impose political requirements on the Argentine provinces, so as to maintain the traditional political and economic preeminence of the capital city. The result was a ten-year separation between the Argentine Confederation and the State of Buenos Aires. Both states claimed to be part of a single nation. But in reality, they behaved like separate states.

The Bombing of Plaza de Mayo was a massacre which took place in Buenos Aires, Argentina, on 16 June 1955. On that day, 30 aircraft from the Argentine Navy and Air Force strafed and bombed Plaza de Mayo square in Buenos Aires in the largest aerial bombing ever on the Argentine mainland. The attack targeted the adjacent Casa Rosada, the official seat of government, as a large crowd was expressing support for president Juan Perón. The strike took place during a day of official public demonstrations to condemn the burning of a national flag allegedly carried out by detractors of Perón during the recent procession of Corpus Christi. The action was to be the first step in an eventually aborted coup d'état. The number of identified bodies was put at 308, including six children; an unknown number of victims could not be identified.The disregard for civilian lives and the violence with which the act was carried out has prompted comparisons with the wave of state terrorism during the dictatorship of 1976-1983.
