The five main leadership styles are authoritarian, participative (or democratic), delegative (laissez-faire), transactional, and transformational. Authoritarian leaders drive decisions from the top, while participative leaders encourage collaboration and input. Delegative leaders give teams full autonomy. Transactional leadership focuses on structure, performance, and rewards, while transformational leadership aims to inspire change through motivation and vision. These styles offer different strengths for managing diverse teams, depending on objectives and organizational context.
