recommended Foucault as head of the Philosophy Department. Becoming a tenured professor of Vincennes, Foucault's desire was to obtain "the best in French philosophy today" for his department, employing Michel Serres, Judith Miller, Alain Badiou, Jacques Rancière, François Regnault, Henri Weber, Étienne Balibar, and François Châtelet; most of them were Marxists or ultra-left activists. Lectures began at the university in January 1969, and straight away its students and staff, including Foucault, were involved in occupations and clashes with police, resulting in arrests. In February, Foucault gave a speech denouncing police provocation to protesters at the Maison de la Mutualité. Such actions marked Foucault's embrace of the ultra-left, undoubtedly influenced by Defert, who had gained a job at Vincennes' sociology department and who had become a Maoist. Most of the courses at Foucault's philosophy department were Marxist–Leninist oriented, although Foucault himself gave courses on Nietzsche, "The end of Metaphysics", and "The Discourse of Sexuality", which were highly popular and over-subscribed. While the right-wing press was heavily critical of this new institution, new Minister of Education Olivier Guichard was angered by its ideological bent and the lack of exams, with students being awarded degrees in a haphazard manner. He refused national accreditation of the department's degrees, resulting in a public rebuttal from Foucault. Later life (1970–1984) Collège de France and Discipline and Punish: 1970–1975 Foucault desired to leave Vincennes and become a fellow of the prestigious Collège de France. He requested to join, taking up a chair in what he called the "history of systems of thought", and his request was championed by members Dumézil, Hyppolite, and Vuillemin. In November 1969, when an opening became available, Foucault was elected to the Collège, though with opposition by a large minority. He gave his inaugural lecture in December 1970, which was subsequently published as L'Ordre du discours (The Discourse of Language). He was obliged to give 12 weekly lectures a year—and did so for the rest of his life—covering the topics that he was researching at the time; these became "one of the events of Parisian intellectual life" and were repeatedly packed out events. On Mondays, he also gave seminars to a group of students; many of them became a "Foulcauldian tribe" who worked with him on his research. He enjoyed this teamwork and collective research, and together they published a number of short books. Working at the Collège allowed him to travel widely,
