The objective of the dissertation is to analyze the concept of sovereignty and the questions that this theme evokes to the political philosophy. Then we have chosen to investigate the evolution of the concept on specifics moments of the classic thought to enlighten raised contemporary formulations and questions on that theme in the present work. Sovereignty exerts wide influence in life in the political community, then to study the questions raised by the subject the dissertation is divided in two parts. The first will provide us with the theoretical base for a consistent analysis on the second part. Given the proportion of the discussion, on the first part, we have limited the study to four classic authors, which are representatives of distinct historic period. Thus we rendered priority to the exposition of the theories on sovereignty, emphasizing due conceptual comprehension of each author and the role of sovereignty in the political organization of the state. The selected authors are: Jean Bodin, Thomas Hobbes, Rousseau and Hegel. In the second part of the dissertation, we move to some authors of the XX and XXI century that produce critics and analysis of the presence of sovereignty in the present. In this point of the dissertation, we limit the study to five authors with important contributions to the discussion, they are: Carl Schmitt, Hannah Arendt, Michael Hardt and Antonio Negri, John Rawls and Giorgio Agamben.
