The Universidad del Salvador (USAL) is a Jesuit university in Buenos Aires, Argentina. In addition to its main Campus, it has instructional and research facilities in Pilar, Buenos Aires; San Miguel, Buenos Aires; Santa Cruz, Misiones; and Bahía Blanca, Buenos Aires. As of 2006 it enrolled approximately 14,000 undergraduate and more than 2,000 graduate students. The Society of Jesus (Jesuits), which had founded the first Argentine university in the city of Córdoba in 1622, created the Superior Institute of Philosophy in the seat of the Colegio del Salvador (primary and secondary levels). This Institute was the nearest predecessor for the Universidad del Salvador. In 1955, private universities were authorized and on May 2 of the following year, the Foundation Act of the "University Faculties of Salvador" was signed. On May 15, 1958 the name was changed to the University Institutes of Salvador, and finally to Universidad del Salvador on December 8, 1959. In March 1975, the Jesuits entrusted management of the university to a group of lay people, who took on the responsibility of keeping the identity of the Universidad del Salvador in meeting their goals and aims.
