Provide some of the examples of regional governments.

Context: Federalism is a combined and compound mode of government that combines a general government with regional governments in a single political system, dividing the powers between the two. Federalism in the modern era was first adopted in the unions of states during the Old Swiss Confederacy.Federalism differs from confederalism, in which the general level of government is subordinate to the regional level, and from devolution within a unitary state, in which the regional level of government is subordinate to the general level. It represents the central form in the pathway of regional integration or separation, bounded on the less integrated side by confederalism and on the more integrated side by devolution within a unitary state.

Answer: provincial, state, cantonal, territorial, or other sub-unit governments
