Treaty of Córdoba
The Treaty of Córdoba established Mexican independence from Spain at the conclusion of the Mexican War of Independence. It was signed on August 24, 1821 in Córdoba, Veracruz, Mexico. The signatories were the head of the Army of the Three Guarantees, Agustín de Iturbide, and, acting on behalf of the Spanish government, "Jefe Político Superior" Juan O'Donojú. The treaty has 17 articles, which developed the proposals of the Plan of Iguala. The Treaty is the first document in which Spanish (without authorization) and Mexican officials accept the liberty of what will become the First Mexican Empire, but it is not today recognized as the foundational moment, since these ideas are often attributed to the Grito de Dolores (September 16, 1810). The treaty was rejected by the Spanish government. Spain did not recognize Mexico's independence until December 1836.
History of Monterrey
After the country's independence from the Spanish Crown and the foundation of Mexico in 1821, the governments of Mexico and the United States fought the Mexican-American War, which resulted in the loss of more than half of Mexico's national territory. On 23 September 1846 General William J. Worth besieged the city and a battle between the two countries was fought from Cerro del Obispado to the Villa de Guadalupe, known as the Battle of Monterrey. American troops remained in the Mexican territory until 1848 and the Mexico-American War ended with the treaty of Guadalupe Hidalgo in which the conflicting parties agreed that the United States would acquire the territories of Alta California and New Mexico, and the territory between the Nueces River and the Rio Grande, claimed by the Republic of Texas.
