International integration refers to the process by which supranational institutions come to replace national ones- the gradual shifting upward of sovereignty from the state to regional or global structures. The ultimate expression of integration would be the merger of several (or many) states into a single state- or ultimately into a single world government. Such a shift in sovereigty to the supranational level would probably entail some version of federalism, in which states (or other political units) would recognize the sovereigty of a central government while retaining certain powers for themselves. This is the form of government adopted in the U.S. Constitution. Today one hears calls for a "United States of Europe" or even of the world, but in practice the process of integration has never gone beyond a partial and uneasy sharing of power between the state and supranational levels. States have been unwilling to give up their exclusive claim to sovereignty and have severely limited the power and authority of supranational institutions.
