The document summarizes several theories of leadership, including:
1. Situational Leadership Theory proposed by Hersey and Blanchard which states leaders should adjust their style based on follower readiness. There are four styles - telling, selling, participating, and delegating.
2. Trait Theory which initially sought to identify innate traits that distinguish leaders but studies found traits did not predict leadership. Later research found honesty, competence, and forward-thinking were admired traits.
3. Behavioral Styles Theory identified two dimensions of leader behavior - consideration for people and initiating structure of tasks. There are four leadership styles depending on levels of each behavior.
