North America 1838: Fragmentation of Central America
A united Central America had broken away from Mexico in 1823, but remained unstable.

Just as the federal government in San Salvador had regained control of Guatemala, Nicaragua and Honduras seceded, followed soon after by Costa Rica. For over a year, civil war raged across the isthmus, before San Salvador finally admitted defeat and let the states go their own way.
