Antonio Negri is an activist, sociologist, philosopher, and one of the central figures of Italian autonomist Marxism. He taught at the University of Padua and the University of Paris VIII. Influenced by his long-standing participation and engagement in political struggles, his work is devoted to studies of political philosophy and the analysis of capitalism and globalization. Among his many publications are Insurgencies: Constituent Power and the Modern State (1999) and Pipeline: Letters from Prison (2015). With Michael Hardt, he co-authored the path-breaking book Empire (2000), followed by Multitude (2004), Commonwealth (2009), and most recently Assembly (2017)—a series that reshaped ways of understanding resistance and revolution in an age of globalization.
