Carmen, Cotabato
Carmen derived its name from a certain Surveyor del Carmen, chief of the Cadastral Survey Party, who in 1924 conducted a survey in the area. During the American period, Carmen and Kabacan belonged to one municipal district under Pikit. It was by virtue of Presidential Proclamation NO. 46 and, was reinforced by Executive Order No. 214 issued by the then President Ramon Magsaysay last November 15, 1956 when Carmen was created as a separate and distinct town of Kabacan.
San Ángel
The modern community has its roots in the establishment of two monastery complexes called San Jacinto and El Carmen in the 16th century, but the real center would be El Carmen. The Spanish town here was originally established with the name of San Jacinto Tenanitla. El Carmen was begun in 1597 when in the indigenous leader of Coyoacán, Felipe de Guzmán Itzolinque, along with Andrés de Mondragón and Elvira Gutierrez, donated lands to the Carmelites in the Tenanitla and Chimalistac areas. The monks used the land to establish their monastery and a school for monks, with the school, named San Ángel, inaugurated in 1613. The monastery and school became wealthy and powerful, mostly due to the productively of the lands, especially the orchards which had, at one time, over 13,000 trees. This prompted the community to rename itself San Ángel.
