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.
