The official coat of arms of the Republic of Costa Rica was designed in 1848, with modifications in 1906, 1964, and 1998. The latest change was the addition of smoke to distinguish the three volcanoes. Before 1821, Costa Rica was part of the Spanish Empire and did not have a local coat of arms. The arms of the reigning monarch were used instead. The only city that had a local coat of arms was the city of Cartago, awarded by King Phillip II in 1565. After independence from Spain in 1821, Costa Rica established different government boards trying to decide its future, debating between being independent (republicans) or join the Mexican Empire (imperialists). Lack of decision led to the Battle of Ochomogo on 5 April 1823, with the decision to remain independent and moving the capital city from Cartago to San José. Due to the long distances and difficult communication at the time, imperialists realized the Mexican Empire no longer existed since March 1823. (Source: Wikipedia.org, CC BY-SA)
