State of Buenos Aires

The State of Buenos Aires (Spanish: Estado de Buenos Aires) was a secessionist republic resulting from the overthrow of the Argentine Confederation government in the Province of Buenos Aires on 11 September 1852. The State of Buenos Aires was never explicitly recognized by the Confederation; it remained, however, independent under its own government and constitution. Buenos Aires rejoined the Argentine Confederation after the former's victory at the Battle of Pavón in 1861.
