A government is the system by which a state or community is governed.
In the case of its broad definition, government normally consists of legisatory, administrators, and arbitrators. Government is the means by which state policy is enforced, as well as the mechanism for determining the policy of the state. A form of government, or form of state governance, refers to the set of political systems and institutions that make up the organisation of a specific government.
States are served by a continuous succession of different governments.
Government of any kind currently affects every human activity in many important ways. For this reason, political scientists generally argue that government should not be studied by itself; but should be studied along with anthropology, economics, history, philosophy, science, and sociology.
Classifying government
In political science, it has long been a goal to create a typology or taxonomy of polities, as typologies of political systems are not obvious.It is especially important in the political science fields of comparative politics and international relations.
On the surface, identifying a form of government appears to be easy, as all governments have an official form. The United States is a federal republic, while the former Soviet Union was a socialist republic. However self-identification is not objective, and as Kopstein and Lichbach argue, defining regimes can be tricky. For example, elections are a defining characteristic of a democracy but in practice elections in the former Soviet Union were not "free and fair" and took place in a single party state. Thus in many practical classifications it would not be considered democratic.
Another complication is that a large number of political systems originate as socio-economic movements and are then carried into governments by specific parties naming themselves after those movements; all with competing political-ideologies. Experience
