Central America, 1825-1838
September 15 is Independence Day in Guatemala, Honduras, El Salvador, Nicaragua, and Costa Rica. And if you’ve ever wondered why all those countries have such similar looking flags, it’s because they were all once part of the same country. The Federal Republic of Central America only lasted for 15 years, but all five successor states kept using the blue-white-blue tricolour.
There were tweaks of course, but they were usually minimal. El Salvador and Nicaragua’s flags are nearly indistinguishable from each other and from the original flag. They both even still say “America Central” on them. Meanwhile Honduras literally just kept flying the old Central American flag for another 30 years. Today Costa Rica’s is the most different; they added a big red stripe during the Revolutions of 1848.
