Europe 1833: Liberal Wars
When King João VI of Portugal died in 1826, a succession dispute arose between the king's eldest son, Pedro—who was Emperor of Brazil—and his next son, Miguel—who claimed Pedro had forfeited his succession rights by declaring Brazil independent. A compromise was reached whereby Miguel would serve as regent for Pedro's young daughter, Maria, but Miguel took this opportunity to seize the throne himself. This led to revolution in Portugal, with the liberal supporters of Pedro eventually defeating the absolutist Miguelists.
