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.
Treaty of Córdoba
On September 27, 1821, the Army of the Three Guarantees entered triumphantly into Mexico City and on the following day, the Declaration of Independence of the Mexican Empire was widely known. The Spanish Cortes refused to accept the validity of the Plan of Iguala or the Treaty of Córdoba. Spain did not recognize Mexico's independence until December 1836. Therefore, the Mexican Congress elected a Mexican monarch the following year. Iturbide was proclaimed emperor of Mexico on May 18, 1822. The monarchy lasted three years, and after the republican revolution of Casa Mata, the Congress no longer considered the Plan of Iguala or Treaty of Córdoba in effect.
