State government
A state government (provincial government in Canada) is the government of a country subdivision 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 which are officially or widely known as "states", and should not be confused with a "sovereign state". Provinces are usually divisions of unitary states. Their governments, which are also provincial governments, are not the subject of this article.
The United States and Australia are the main examples of federal systems in which the term "state" is used for the subnational components of the federation. In addition, the Canadian provinces fulfil a similar role. The term for subnational units in non-English-speaking federal countries may also often be translated as "state", e.g. States of Germany (German Länder).
State governments of the United States
State governments of the United States include the governments of the original thirteen states and the governments of the remaining thirty seven which were admitted to the United States as authorized under Article IV, Section 3, of the Constitution of the United States.
While state governments within the United States may enact their own laws and prosecute crimes pursuant thereto, they are not sovereign in the Westphalian sense in international law which says that each State has sovereignty over its territory and domestic affairs, to the exclusion of all external powers, on the principle of non-interference in another State's domestic affairs, and that each State (no matter how large or small) is equal in international law. Additionally, the member states of the United States do not possess international legal sovereignty, meaning that they are not recognized by other sovereign States such as, for example, France, Germany or the United Kingdom, nor do they possess full interdependence sovereignty (a term popularized by international relations professor Stephen D. Krasner), meaning that they cannot control movement of persons across state borders.
