In the 1960s, due to the extension of compulsory school attendance and the subsequent liberalisation of access to higher education, the number of people entering Italian universities progressively increased and the University of Milan enrolled more than 60,000 students. The University added to its range of courses and at the same time increased its number of centres. Two new schools were established, Pharmacy and Social and Political Sciences, which were based, respectively, in Città Studi and in "Via Conservatorio", in Milan city centre.
