On 11 March 1747 the Royal University of San Felipe was formally established. That day its main promoter, Tomás de Azúa, was elected its first rector. However, classes did not start until 9 January 1758, 11 years later, with a course of law. As expected, it was guided by the parameters established for the oldest universities of Spanish America, such as the
University of San Marcos in
Lima,
Del Rosario University in
Bogotá, and the original
University of Mexico. Through the University of San Marcos it received access to resources of the
University of Salamanca, Spain. The real organizer of the university is considered to be Valeriano de Ahumada y Ramírez de Carvajal, a learned scholar who was its vice chancellor from 1757 to 1765, and third rector from 1758 to 1759. He organized courses, controlled the attendance of students and teachers, and was a tenacious opposer of the awarding of titles to those who did not meet academic requirements (buying degrees was common at that time).
Paseo Ahumada, a street in downtown Santiago, was named in honor of him and his ancestors. The university superseded or continued the work done by the Dominicans of the , and after the expulsion of the Jesuits in 1767, acquired the goods and students of the
Convictorio Carolino. Like its counterparts in Mexico and Lima, the University of San Felipe had faculties of Theology, Philosophy, Law, Medicine, and Mathematics. It continued in this capacity until 1813, when the university began a process of change as a result of the political independence of Chile. The university library amassed a significant collection, noted for its “curious" manuscripts relating to indigenous peoples, donated by the Jesuits. The personal collection of
Mariano Egaña was donated upon his death in 1846. In 1852, the library formed the basis of the
Biblioteca Nacional de Chile. The institution's structure diminished and ossified. This process led, in 1843, to the founding of the
University of Chile, an institution which more closely adhered to cultural and educational ideals of
republican society. ==Transition to the University of Chile==
