Origin

Political science is a social science dealing with systems of governance and power, and the analysis of political activities, political institutions, political thought and behavior, and associated constitutions and laws.

As a social science, contemporary political science started to take shape in the latter half of the 19th century and began to separate itself from political philosophy and history. Into the late 19th century, it was still uncommon for political science to be considered a distinct field from history. 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.

Generally, classical political philosophy is primarily defined by a concern for Hellenic and Enlightenment thought, political scientists are also marked by a great concern for " modernity " and the contemporary nation state, along with the study of classical thought, and as such share more terminology with sociologists (e.g., structure and agency).

The advent of political science as a university discipline was marked by the creation of university departments and chairs with the title of political science arising in the late 19th century. The designation "political scientist" is commonly used to denote someone with a doctorate or master's degree in the field. Integrating political studies of the past into a unified discipline is ongoing, and the history of political science has provided a rich field for the growth of both normative and positive political science, with each part of the discipline sharing some historical predecessors. The American Political Science Association and the American Political Science Review were founded in 1903 and 1906, respectively, in an effort to distinguish the study of politics from economics and other social phenomena. APSA membership rose from 204 in 1904 to 1,462 in 1915. APSA members played a key role in setting up political science departments that were distinct from history, philosophy, law, sociology, and economics.

The journal Political Science Quarterly was established in 1886 by the Academy of Political Science. In the inaugural issue of Political Science Quarterly, Munroe Smith defined political science as "the science of the state. Taken in this sense, it includes the organization and functions of the state, and the relation of states one to another."

As part of a UNESCO initiative to promote political science in the late 1940s, the International Political Science Association was founded in 1949, as well as national associations in France in 1949, Britain in 1950, and West Germany in 1951.
