Devolution refers to the process where regions within a state gain more autonomy and political power at the expense of the central government, potentially leading to the disintegration of the state along regional lines. Examples include Scotland seeking independence from the UK, the peaceful split of Czechoslovakia in 1993, and the breakup of Yugoslavia into independent states. Supranationalism refers to the formation of unions between three or more states to pursue shared economic, political, and cultural goals for mutual benefit. Current examples of supranational organizations include the European Union, United Nations, NATO, OPEC, and the Arab League.
