The theme of the political party in Michel Foucault's analyses has failed to elicit the kind of elaborate attention that has been bestowed on his analyses of other core political concepts. This lack of attention no doubt reflects Foucault's lack of an elaborate analysis of the party. He never theorized the party at much length, and his discussions of it tended to occupy a place on the margins of his analyses. But the party figured as a recurrent theme in his Collège de France courses from the late 1970s to early 1980s, even as these courses addressed remarkably diverse topics across a vast expanse of time and space. What is more, Foucault announced his intention to conduct research on the party and encouraged his auditors to do likewise. Toward the end of his life, Foucault even began to read the writings of prominent French Socialist Party (PS) leaders for the purpose of producing a whole book on the PS.
