As of 2014, an example of an unlimited government is North Korea. In the past, other examples of this form of government were Germany under Adolf Hitler and the Soviet Union under Joseph Stalin's rule. An unlimited government is one in which one person or a group is in complete control.
A totalitarian system is a type of unlimited government. Other forms of unlimited governments can include authoritarian systems, dictatorships and military juntas.
The difference between an unlimited and a limited government is that a limited government has checks and balances that control the powers of people in authority, meaning those who run the government. The United States is an example of a limited government in which Congress and the president must follow laws established by the U.S. Constitution.
