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 Mexico City
In 1910, Mexico celebrated the 1810 Hidalgo revolt that initiated the independence movement in Mexico. Díaz had been in power since 1876 and saw the occasion of the centenary as an opportunity for the creation of new buildings and monuments and to invite world dignitaries to show off Mexico's progress. For buildings, much advance planning and other work was needed to have them completed in time for September 1910. During that month in Mexico City, there were "inaugurations of a new modern mental hospital, a popular hygiene exhibition, an exhibition of Spanish art and industry, exhibitions of Japanese products and avant-garde Mexican art, a monument to Alexander von Humboldt at the National Library, a seismological station, a new theater in the Escuela Nacional Preparatoria, primary schools, new buildings for ministries, and new large schools for teachers." On the actual anniversary of Hidalgo's "grito", 16 September, Díaz inaugurated the monument to Independence, "the Angel".
