A government is the system or group of people governing an organized community, generally a state.
In the case of its broad associative definition, government normally consists of legislature, executive, and judiciary.
Government is a means by which organizational policies are enforced, as well as a mechanism for determining policy.
Each government has a kind of constitution, a statement of its governing principles and philosophy.
While all types of organizations have governance, the term government is often used more specifically, to refer to the approximately 200 independent national governments and subsidiary organizations.
Historically prevalent forms of government include monarchy, aristocracy, timocracy, oligarchy, democracy, theocracy and tyranny.
The main aspect of any philosophy of government is how political power is obtained, with the two main forms being electoral contest and hereditary succession.
