History of Mexico

Highly developed cultures, including those of the Olmecs, Mayas, Toltecs, and Aztecs existed long before the Spanish conquest. Hernando Cortes conquered Mexico during the period 1519-21 and founded a Spanish colony that lasted nearly 300 years. Independence from Spain was proclaimed by Father Miguel Hidalgo on September 16, 1810; this launched a war for independence. An 1821 treaty recognized Mexican independence from Spain and called for a constitutional monarchy. The planned monarchy failed; a republic was proclaimed in December 1822 and established in 1824.

Prominent figures in Mexico's war for independence were Father Jose Maria Morelos; Gen. Augustin de Iturbide, who defeated the Spaniards and ruled as Mexican emperor from 1822-23; and Gen. Antonio Lopez de Santa Ana, who went on to control Mexican politics from 1833 to 1855. Santa Ana was Mexico's leader during the conflict with Texas, which declared itself independent from Mexico in 1836, and during Mexico's war with the United States (1846-48).
