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.
American frontier
Mexico became independent of Spain in 1821, and took over Spain's northern possessions stretching from Texas to California. Caravans began delivering goods to Mexico's Santa Fe along the Santa Fe Trail, over the journey which took 48 days from Kansas City, Missouri (then known as Westport). Santa Fe was also the trailhead for the "El Camino Real" (the King's Highway), a trade route which carried American manufactured goods southward deep into Mexico and returned silver, furs, and mules northward (not to be confused with another "Camino Real" which connected the missions in California). A branch also ran eastward near the Gulf (also called the Old San Antonio Road). Santa Fe connected to California via the Old Spanish Trail.
