Antonio Negri’s thought is a reflection on the concept of sovereignty. Since the end of the 1950s until the most recent texts, Negri works on and against the concept of sovereignty, identifying limits, breaches and advances through the critique of political economy. In this paper we consider some texts of a very large production, that allow us to highlight these crucial elements. From the essays of philosophy of law in La Forma Stato, passing through the pamphlets contained in 'I libri del rogo', from the intellectual production during 1980s and 1990s, until Empire. These are phases that coincide with the end of the – so called by Negri – planner-State and with the birth of the Stato-crisi, stages whose latest development is the emersion of a new global order after the fall of the Sovietic Union and the end of the Cold War.
