The Ochomogo War was a civil war fought in Costa Rica, the first in its history, and was fought shortly after the country became independent from Spain. The most important event was the Battle of Ochomogo (5 April 1823) which was fought on Ochomogo Hill, from which it takes it name, to the west of Cartago, Costa Rica. Republican militia from San José and Alajuela led by Gregorio José Ramírez defeated conservative forces from Cartago, the colonial capital, who supported making Costa Rica part of the new Mexican Empire. The Republicans won the battle and San José became capital of the country, which remained independent within the Federal Republic of Central America.
