Spanish attempts to reconquer Mexico
Mexican independence was officially achieved on September 27, 1821, under the Treaty of Córdoba. Spain did not recognize the treaties, arguing that the viceroy Juan O'Donojú had no authority to recognize the independence of any overseas province. This situation was dangerous to the newly acquired independent status of the nation, which had not yet been recognized by any of the European powers that could support it, and the threat of Spanish reconquest was a constant worry to the leaders of the nascent regime. On May 13, 1822 decrees were issued by the government to imprison anyone who conspired against Mexico's independence.
José María Morelos
On September 31, 1813, the Congress, with Morelos present, endorsed the "Sentiments of the Nation". This document declared Mexican independence from Spain, established the Roman Catholic religion and created the legislative, executive and judicial branches of government. It declared respect for property and confiscated the productions of the Spanish colonial government. It abolished slavery and racial social distinctions in favor of the title "American" for all native-born individuals. Torture, monopolies and the system of tributes were also abolished. Morelos was offered the title "Generalissimo" with the style of address "Your Highness", but he refused these and asked to be called "Siervo de la Nación" (Servant of the Nation). On November 6, 1813 the Congress declared independence.
