Army of the Three Guarantees
During the colonial period, the area not underwater was home to haciendas, resulting from the partition of lands among the conquistadors and their descendants. In 1709, Azcapotzalco was formed by 27 communities, divided into six haciendas and nine ranches. Azcapotzalco was the scene of one of the last battle of the Mexican War of Independence with the Army of the Three Guarantees under Anastasio Bustamante defeating royalist forces on August 19, 1821, shortly before Agustín de Iturbide entered Mexico City.
