While the term "political science" as a separate field is a rather late arrival in terms of social sciences, analyzing political power and the impact that it had on history has been occurring for centuries. However, the term "political science" was not always distinguished from political philosophy, and the modern discipline has a clear set of antecedents including moral philosophy, political economy, political theology, history, and other fields concerned with normative determinations of what ought to be and with deducing the characteristics and functions of the ideal state.
