Leadership is both a research field and a practical skill encompassing the ability of an individual or organization to "direct" or guide different individuals, groups, or entire organizations. Specialist literature debates various perspectives, contrasting Eastern and Western approaches to leadership, and also (inside the West) US vs. European approaches. US academic surroundings define leadership as "a process of social influence in which a person can enlist the aid and support of other people in the accomplishment of a frequent task".

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

Studies of leadership have produced theories involving traits, situational interaction, role, behavior, ability, vision and values, charisma, and intelligence, amongst others.

A leadership style is a pioneer's style of offering direction, executing plans, and motivating people. It's the doctrine, character, and experience of the leader's end result. Rhetoric experts 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 little time to converge on an agreement and at which a designated authority has significantly more experience or experience than the remainder of the group, an autocratic leadership style could be best; however, in an extremely motivated and adapting staff using a homogeneous degree of expertise, a more democratic or Laissez-faire style may be more effective. The design adopted should be the one that most effectively achieves the aims of the group whilst balancing the interests of its unique members.

A discipline in which leadership style has gained powerful focus is that of military science, recently expressing a holistic and integrated perspective of leadership, including how a leader's physical existence determines how others perceive that pioneer. The variables of physical presence are military bearing, physical fitness, confidence, and resilience. The leader's intellectual capacity helps to conceptualize alternatives and acquire knowledge to perform the job. A leader's conceptual abilities employ agility, judgment, invention, social tact, and domain knowledge. Domain knowledge for leaders encompasses technical and tactical knowledge in addition to cultural and geopolitical significance.
