Politics (from Greek πολιτικός, "of, for, or relating to citizens"), is a process by which groups of people make collective decisions. The term is generally applied to the art or science of running governmental or state affairs. It also refers to behavior within civil governments. However, politics can be observed in other group interactions, including corporate, academic, and religious institutions. It consists of "social relations involving authority or power" and refers to the regulation of public affairs within a political unit, and to the methods and tactics used to formulate and apply policy
