Leadership is both a research area and a practical ability encompassing the capability of an individual or organization to "direct" or guide different people, groups, or entire organizations. Professional literature debates various perspectives, contrasting Eastern and Western approaches to leadership, and (within the West) US vs. European approaches. US academic surroundings define leadership as "a process of social influence in which a individual could enlist the aid and support of other people in the accomplishment of a common task".

Leadership seen from a non-academic perspective encompasses a view of a leader who could be transferred not only by communitarian goals but also by the search for personal power. Leadership can derive from a combination of many factors.

Studies of leadership have generated theories involving traits, behavioural discussion, function, behaviour, ability, vision and values, charisma, and intelligence, among others.

A leadership style is a leader's style of providing management, executing plans, and motivating people. It's the doctrine, character, and experience of the leader's end result. Rhetoric specialists have also developed models for understanding leadership (Robert Hariman, Political Style, Philippe-Joseph Salazar, L'Hyperpolitique. Technologies politiques De La Domination).

Different situations call for different leadership styles. In a crisis when there is minimal time to converge on an arrangement and where a designated authority has much more experience or experience than the remainder of the team, an autocratic leadership style may be most effective; however, at an extremely motivated and adapting staff with a homogeneous degree of expertise, a more democratic or Laissez-faire style might be more successful. The style adopted should be the one that most effectively achieves the aims of the group whilst balancing the interests of its unique members.

A discipline where leadership style has gained strong focus is that of military science, recently expressing a holistic and integrated perspective of leadership, such as the way the leader's physical existence determines how others perceive that leader. The factors of physical presence are military posture, physical fitness, confidence, and endurance. The leader's intellectual capability helps to conceptualize alternatives and acquire knowledge to perform the job. A leader's conceptual skills apply agility, judgment, innovation, social tact, and domain knowledge. Domain knowledge for leaders encircles technical and tactical knowledge in addition to cultural and geopolitical awareness.
