It is usually compared to the legal system, economic system, cultural system, and other social systems. According to David Easton, "A political system can be designated as the interactions through which values are authoritatively allocated for a society." Each political system is embedded in a society with its own political culture, and they in turn shape their societies through public policy. The interactions between different political systems are the basis for global politics.
