After the Conquest, Apochquiyauhtzin, the last lord of Xochimilco, was baptized with the name of Luís Cortés Cerón de Alvarado in 1522 and he was allowed to continue governing under the Spanish. Evangelization was undertaken here by Martín de Valencia with a number of others who are known as the first twelve Franciscans in Mexico. Their monastery was built between 1534 and 1579, along with many chapels and churches in the Xochimilco area, a hospital in Tlacoapa and a school. Xochimilco was made an encomienda of Pedro de Alvarado in 1521 and remained such until 1541.
