The Complutense University of Madrid (''Universidad Complutense de Madrid''; UCM) is the second largest university in Spain after UNED and one of the oldest universities in the world. It has over 11,000 staff members and a student population of 117,000. Most of the academic staff is Spanish. It is located on two campuses, the main one of Ciudad Universitaria in the Moncloa-Aravaca district, and the secondary campus of Somosaguas, located outside the city limits in Pozuelo de Alarcón and founded in 1971. The Complutense University of Madrid was founded in Alcalá de Henares, old Complutum, by Cardinal Cisneros in 1499. Nevertherless, its real origin dates back to 1293, when King Sancho IV of Castile built the General Schools of Alcalá, which would give rise to Cisnero's Complutense University. During the course of 1509–1510 five schools were already operative: ''Artes y Filosofía'' (Arts and Philosophy), ''Teología'' (Theology), ''Derecho Canónico'' (Canonical Laws), ''Letras'' (Liberal Arts) and ''Medicina'' (Medicine). In 1836, during the reign of Isabel II, the university was moved to Madrid, where it took the name of Central University and was located at San Bernardo Street. Subsequently, in 1927, a new University City (Ciudad Universitaria) was planned to be built in the district of Moncloa-Aravaca, in lands handed over by the King Alfonso XIII to this purpose. The Spanish Civil War turned the University City into a war zone, causing the destruction of several schools in the area, as well as the loss of part of its rich scientific, artistic and bibliographic heritage.
