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.
New Spain
In the 1821 Declaration of Independence of the Mexican Empire, both Mexico and Central America declared their independence after three centuries of Spanish rule and formed the First Mexican Empire, although Central America quickly rejected the union. After priest Miguel Hidalgo y Costilla's 1810 Grito de Dolores (call for independence), the insurgent army began an eleven-year war. At first, the Criollo class fought against the rebels. But in 1820, a military coup in Spain forced Ferdinand VII to accept the authority of the liberal Spanish Constitution. The specter of liberalism that could undermine the authority and autonomy of the Roman Catholic Church made the Church hierarchy in New Spain view independence in a different light. In an independent nation, the Church anticipated retaining its power. Royalist military officer Agustín de Iturbide proposed uniting with the insurgents with whom he had battled, and gained the alliance of Vicente Guerrero, leader of the insurgents in a region now bearing his name. Royal government collapsed in New Spain and the Army of the Three Guarantees marched triumphantly into Mexico City in 1821.
