On February 1, 1979, the Ayatollah Khomeini returned to Iran after fifteen years of exile [and] was acclaimed the leader of the Iranian Revolution. Later that year revolutionary students would storm the U.S. embassy in Tehran and take the staff hostage, to profound consequence. One observer of the Iranian Revolution was Michel Foucault, who was a special correspondent for Corriere della Sera and le Nouvel Observateur, for whom he wrote a series of articles. In Foucault and the Iranian Revolution: Gender and the Seductions of Islamism, Janet Afary and Kevin B. Anderson illuminate Foucault's support of the Islamist movement and show how Foucault's experiences in Iran contributed to a turning point in his thought.
