José Joaquín de Arredondo
When Mexico achieved independence from Spain, Arredondo offered on July 3, 1821 to swear fealty to the new government if he could retain his office as commandant general; his offer was rejected by the citizens of Satillo, and Agustín de Iturbide's "Plan de Iguala" for Mexican independence led to his removal from power. Arredondo is remembered in Texas history as a "butcher" because of his executions of republicans.
When Mexico achieved independence from Spain, Arredondo endorsed the Plan of Iguala and swore allegiance to the Republic of Mexico on July 3, 1821. He surrendered his command, went into retirement in Havana, Cuba, and died in 1837 shortly after Texas had gained its independence.
Emperor
In Mexico, the First Mexican Empire was the first of two empires created. After the declaration of independence on September 15, 1821, it was the intention of the Mexican parliament to establish a commonwealth whereby the King of Spain, Ferdinand VII, would also be Emperor of Mexico, but in which both countries were to be governed by separate laws and with their own legislative offices. Should the king refuse the position, the law provided for a member of the House of Bourbon to accede to the Mexican throne.
