A state government is the government that controls a subdivision of a country in a federal form of government, which shares political power with the federal or national government. A state government may have some level of political autonomy, or be subject to the direct control of the federal government. This relationship may be defined by a constitution.
The reference to "state" denotes country subdivisions that are officially or widely known as "states", and should not be confused with a "sovereign state". Most federations designate their federal units "state" or the equivalent term in the local language; however, in some federations, other designations are used such as Oblast or Republic. Some federations are asymmetric, designating greater powers to some federal units than others.
