Leadership can be defined as encouraging and helping others work towards common goals. Effective leadership styles depend on the situation and maturity of followers. Theories of leadership include trait, behavioral, contingency, and path-goal theories. Trait theories focus on innate qualities of leaders while behavioral theories examine how leader behaviors impact followers. Contingency theories stress that leadership effectiveness depends on matching style to the context. The path-goal theory holds that leaders clarify goals and remove obstacles for followers.
