This essay analyzes the creation and disappearance of States, and describes the International Law norms and principles that regulate the consequences of such events. It details the different ways by which such processes may occur, and illustrates each of them with various historical examples. It also examines the problem of determining the identity that may or may not exist between a new State and an extinct one, and explains the norms and criteria that ascertain whether there is continuity or not between both entities.
