[The historical environment from which Social Service emerged].

The historic background in which Social Service appeared dates back to the time when L. Cárdenas (1934-1940) was president of Mexico. In 1935, the reaction of the University to the reformation of article 3 was considered as an antirevolutionary behavior and was seen as opposite to the State's education project. Our history begins in this scenario. During L. Chico Goerne's term, the University signs a new agreement with the Government in which, among other things, the Social Service as a mandatory requirement to obtain a university degree is established. Thus, the mandatory Social Service organized by G. Baz, director of the Facultad de Medicina, who reinforced it as the University rector. Since the establishment of the Social Service, the University did not have to fight for financial support and also restored its prestige and social usefulness before the government that used to exclude the University from its project.
