flag of Nicaragua

Independence for Central America was first proclaimed on September 15, 1821, but Mexico then subdued the area for two years. The flag of the newly independent United Provinces of Central America was adopted on August 21, 1823, and consisted of blue-white-blue stripes with the national coat of arms in the centre. Those arms included basically the same design elements Nicaragua uses today. Even after the five member states of the federation became independent countries, Nicaragua continued to hoist the old flag. Finally, in 1854, a new horizontal Nicaraguan tricolour of yellow-white-scarlet was chosen, but it did not fly for long. Civil war and intervention by North American filibusters (military adventurers) subsequently resulted in a number of flags being introduced and quickly replaced.

In 1908 the old federation flag was readopted as the national banner of Nicaragua, with appropriate modifications in the coat of arms. That basic design, with further changes to the coat of arms, was reaffirmed by the law of August 27, 1971, although the red-black horizontal bicolour of the Sandinista movement was de facto a secondary national flag during the years of Sandinista rule (1979–90). The coat of arms on the flag includes a triangle for equality, a liberty cap for freedom, and five volcanoes between two oceans, symbolic of the five original Central American countries between the Atlantic and Pacific ocean basins.
