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.
Central America
The Captaincy General of Guatemala lasted for more than two centuries, but began to fray after a rebellion in 1811 which began in the intendancy of San Salvador. The Captaincy General formally ended on 15 September 1821, with the signing of the Act of Independence of Central America. Mexican independence was achieved at virtually the same time with the signing of the Treaty of Córdoba and the Declaration of Independence of the Mexican Empire, and the entire region was finally independent from Spanish authority by 28 September 1821.
