Power refers to the potential ability of an individual or group to influence or control others. It is based on the dependence of one party on another. There are five bases of power: coercive, reward, legitimate, expert, and referent. Leadership differs from power in that leadership requires coordination between the goals of the leader and followers through downward influence, while power focuses on gaining compliance through any means. Leadership research examines how supportive and inclusive a leader should be, unlike power research which centers on control tactics.
