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., provinces, states, cantons, territories, etc.), while dividing the powers of governing between the two levels of governments. Two illustrative examples of federated countriesāone of the world's oldest federations, and one recently organizedāare Australia and Micronesia.
Johannes Althusius (1563ā1638) is considered the father of modern federalism, along with Montesquieu. In 1603, Althusius first described the bases of this political philosophy in his Politica Methodice Digesta, Atque Exemplis Sacris et Profanis Illustrata. 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.
