when did political science become an academic discipline
Political science As a social science, contemporary political science started to take shape in the latter half of the 19th century. At that time it began to separate itself from political philosophy, which traces its roots back to the works of Chanakya, Aristotle, and Plato which were written nearly 2,500 years ago. The term "political science" was not always distinguished from political philosophy, and the modern discipline has a clear set of antecedents including also 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.
Politics Among Nations The book introduces the concept of political realism, presenting a realist view of power politics. This concept played a major role in the foreign policy of the United States, which made it exercise globe-spanning power in the Cold War period. The concept also called for a reconciliation of power politics with the idealistic ethics of earlier American discussions about foreign policy.
