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.
A political science degree can often lead to a career in business, with banking, advertising, personnel and public relations as possible employment goals. Political science students seeking to enter the business world usually need superb verbal and written communication skills as well as a high-level understanding of mathematics and economics. Computers skills are also valuable in business professions. This is a very competitive field, and a graduate degree, while not a strict requirement, can be an aid in job acquisition and might lead to advanced positions, such as corporate management.
