Political map of South American nations 02 November 1874 (Argentine Civil Wars): The reunification of Argentina in 1861 (Argentine Civil Wars) did not bring stability to the country, which continued to suffer from military coups, uprisings, and Indian tribal raids through into the 1870s. In 1874, former president Bartolomé Mitre led an unsuccessful revolution against the Argentine government in the aftermath of a disputed election; six years later, Buenos Aires province itself would revolt after another election (Carlos Tejedor (politician)).
