Political system is one of the subsystem of society, and play sufficient role in our life.
The term political system refers to a recognized set of procedures for implementing and obtaining the objectives of the group.
Each society must have a political system in order to maintain recognized procedures for the allocation of resources. In political scientist Harold Lasswell (1936) terms, the policy of the who, what, when and how. Thus, like religion and the family, the political system is a cultural universal, is a social institution, in every society.
We will focus on government and politics within the United States as well as other industrialized nations and preindustrial societies. In their study of politics and political systems, sociologists are concerned with social interactions among individuals and groups and their impact on the larger political order. For example, in studying the controversy over the nomination of Judge Robert Bork, sociologists might wish to focus on how a change in the group structure of American society—the increasing importance of the black vote for southern Democratic candidates—affected the decision making of Howell Heflin and other senators (and, ultimately, the outcome of the Bork confirmation battle). From a sociological perspective, therefore, a fundamental question is: how do a nation's social conditions affect its day-to-day political and governmental life?
Power in the center of the political system. Power can be defined as the ability to exercise their will over others. In other words, if one of the parties in a relationship can control the behavior of others, that person or group of persons exercising power. Power relations can involve large organizations, small groups, or even people in an intimate association. Blood and Wolfe (1960) devised the concept of marital power to describe the manner in which decision making is distributed within families.
