Political Science is the systematic study of politics, power relationships and government. Political science is in one sense an ancient discipline: Aristotle called it the "queen of the sciences." Yet the focus for much of today's political science was developed in the last century. Scientific observations have now joined older philosophical traditions. Modern political science examines politics in the Untied States, countries and regions of the world and in international relations. It explains how and why public decisions are made. Political Science majors can qualify for a wide variety of careers in public and private sector organizations, including business, law, government, journalism, international organizations and finance, political campaigns, interest groups and secondary and college teaching. The study of public affairs and government is essential for developing effective citizenship. This training prepares one for professional or volunteer involvement in community organizations, issue movements, electoral politics, and other activities in the public arena.
