Ejército Trigarante
It was not until late 1820, when Agustín de Iturbide, one of the most bloodthirsty enemies of the insurgents, established relations with Vicente Guerrero and Guadalupe Victoria, two of the rebel leaders. Guerrero and Victoria supported Iturbide's plan for Mexican independence, El Plan de Iguala and Iturbide was appointed commander of the Ejército Trigarante, or "The Army of the Three Guarantees". With this new alliance, they were able to enter Mexico City on 27 September 1821, which concluded the Mexican War for Independence.
