Federalism

Federalism is a mode of government that combines a general level of government (a central or federal government) with a regional level of sub-unit governments (e.g., counties, provinces, states, cantons, territories, etc.), while dividing the powers of governing between the two levels of governments.

Johannes Althusius (1563–1638) is considered the father of modern federalism, along with Montesquieu. By 1748, in his treatise The Spirit of Law, Montesquieu (1689–1755) observed various examples of federalist governments: in corporate societies, in the polis bringing villages together, and in cities themselves forming confederations. In the modern era, federalism was first adopted by a union of the states of the Old Swiss Confederacy as of the mid-14th century.

Federalism differs from confederalism, where the central government is created subordinate to the regional states—and is notable for its regional separation of governing powers (e.g., in the United States, the Articles of Confederation as the general level of government of the original Thirteen Colonies). Federalism also differs from the unitary state, where the regional level is subordinate to the central government, even after a devolution of powers (e.g., the United Kingdom).

Examples of federalism today include: Argentina, Australia, Brazil, Canada, Ethiopia, Germany, India, Iraq, Malaysia, Mexico, Switzerland, the United Arab Emirates, and the United States. At a multi-state level, the European Union has been characterized by some as a federation.
