Political science is a social science discipline that deals with systems of government, and the analysis of political activities, political thoughts and political behaviour. It deals extensively with the theory and practice of politics which is commonly thought of as determining of the distribution of power and resources. Political scientists "see themselves engaged in revealing the relationships underlying political events and conditions, and from these revelations they attempt to construct general principles about the way the world of politics works." Political science is related to and draws upon the fields of economics, law, sociology, history, philosophy, geography, psychology, and anthropology.
