To consider Political Science as a study of State and government is an institutional approach to the study of Political Science. It is, however, a partial view of it. Politics is a dynamic process, a power process. It is a relation in which one “actor” influences the behaviors of another. “Political Process” means the activities of the people organized in various groups, such as parties, factions, or leaders of parties, factions or cliques or groups, who struggle for and use power to achieve personal and group purposes by attaining position of authority in the government, whether it is unitary, federal, provincial or local.
It involves conflict which may include not only violence, propaganda, pressure, guiles and frauds and character assassination, but also slow building of consensus, and public opinion. By power is meant the capacity to influence events and thereby to control the behavior of others. The greater the influence, the greater the power and ultimately the greater the actor.
Without power no leader, or ruler can realize his own interests or the interests of a small minority or of his country. But the real test of power is the purpose for which it is used, or the interests it seeks to satisfy. Political process operates in a system, in which Power achievement is an input and the satisfaction of interests, personal, of *e group or nation, is the output. It makes political science a study of political system, which we shall study later on.
