What is Sovereignty

The concept of sovereignty is one of the most complex in political science, with many definitions, some totally contradictory.1 Usually, sovereignty is defined in one of two ways. The first definition applies to supreme public power, which has the right and, in theory, the capacity to impose its authority in the last instance. The second definition refers to the holder of legitimate power, who is recognized to have authority. When national sovereignty is discussed, the first definition applies, and it refers in particular to independence, understood as the freedom of a collective entity to act. When popular sovereignty is discussed, the second definition applies, and sovereignty is associated with power and legitimacy.
