One of the most intriguing expressions of human behavior is the leader-follower phenomenon. Since the beginning of civilization, people have sought answers to the questions of who becomes a leader and why. Philosophers, political scientists, and psychologists have produced extensive literature on leaders and leadership, but despite this, there is still no consensus as to why and under what circumstances some become leaders and others remain followers. There is no universal theory of leadership and no precise formula for producing leaders, and the answers are elusive. Furthermore, the debate continues about whether effective leadership and successful management are synonymous. Perhaps one of the best ways to answer
some of these questions is to describe some of the views about leadership. This provides a beginning for defining leadership, for explaining the power associated with it, for discussing the various current theories about it and for determining where theories coalesce and diverge.
