Foucauldian Genealogy and Maoism

If we look at the historical and social presuppositions of Foucault's methodology, we find out that Nietzsche's work cannot be the only root of the shift from archaeology to genealogy. In fact, a whole range of political activist practices after May '68 until the dissolution of the Groupe d'information sur les prisons (GIP) played an important role in inciting a politicization-in-motion that clearly left its traces in Foucault's thought and work.
