During the Spanish Conquest, Gonzálo de Sandoval and his Otomi allies, conquered Toluca, Tenango, Tlacotepec, Tecaxic-Calixtlahuaca, Calimaya along with Metepec and other Matlatzinca and Mexica population centers, whose lands were then abandoned by the natives. These lands were then redistributed among the Spaniards who participated in the Conquest and to those local chiefs that supported the Spanish. Lands in and around Metepec were given to Captain Juan Gutiérrez Altamirano, who brought the Franciscans in to evangelize the area, and then these lands passed on to form the estates of the Counts of Santiago. The area was considered an "alcaldía mayor" (literally 'major mayorship') by 1560 with the village of Metepec as its seat. Records of municipal government transactions begin in the 19th century. Finally, the municipality of Metepec was created in 1821; although this was not ratified by the government of the State of Mexico until 1827.
