Mexico
Mexico's war of independence began with the priest Miguel Hidalgo's call to revolt in 1810 and ended in 1821, when the royalist officer Agustín de Iturbide joined the rebels; he briefly reigned as emperor, and Central America broke away in 1823. The young republic was unstable, and under the strongman Santa Anna it lost Texas in 1836 and, after war with the United States in 1846–48, about half its territory.
Benito Juárez's liberal reforms provoked civil war and a French invasion that installed the Austrian archduke Maximilian as emperor, executed in 1867. Porfirio Díaz then ruled for over three decades, building railways but concentrating land and wealth. The Mexican Revolution of 1910–20 overthrew him, and the party later called the Institutional Revolutionary Party governed from 1929 until the elections of 2000.
