Agustín Cosme Damián de Iturbide y Aramburu (27 September 1783 – 19 July 1843) was a Mexican army general who built a successful political and military coalition that was able to march into Mexico City on 27 September 1821, decisively ending the Mexican War of Independence. After the liberation of Mexico was secured, he was proclaimed President in 1821. He ruled with a hard hand, as a dictator. A coup by Antonio Lopez de Santa Anna in 1828 failed and he fled to Central America. Iturbide was firm in power until 1830 when some generals deposed of him and he fleed to the United States. In 1833 he returned with a force and deposed Santa Anna. This started that Mexican Civil War and only until 1835 was he complete controll of Mexico. In 1836 he made himself King Agustin I of Mexico (Agustin I de Mexico, Yucatan y todas las Californias). In 1843 he was assassinated and succeded by Santa Anna.
