Leadership has been described as “a process of social influence in which one person can enlist the aid and support of others in the accomplishment of a common task". Other in-depth definitions of leadership have also emerged.
Leadership is "organizing a group of people to achieve a common goal". The leader may or may not have any formal authority. Studies of leadership have produced theories involving traits, situational interaction, function, behavior, power, vision and values, charisma, and intelligence, among others. Somebody whom people follow: somebody who guides or directs others.

Early western history
The search for the characteristics or traits of leaders has been ongoing for centuries. History's greatest philosophical writings from Plato's Republic to Plutarch's Lives have explored the question "What qualities distinguish an individual as a leader?" Underlying this search was the early recognition of the importance of leadership and the assumption that leadership is rooted in the characteristics that certain individuals possess. This idea that leadership is based on individual attributes is known as the "trait theory of leadership".
​
The trait theory was explored at length in a number of works in the 19th century. Most notable are the writings of Thomas Carlyle and Francis Galton, whose works have prompted decades of research. In Heroes and Hero Worship (1841), Carlyle identified the talents, skills, and physical characteristics of men who rose to power. In Galton's Hereditary Genius (1869), he examined leadership qualities in the families of powerful men. After showing that the numbers of eminent relatives dropped off when moving from first degree to second degree relatives, Galton concluded that leadership was inherited. In other words, leaders were born, not developed. Both of these notable works lent great initial support for the notion that leadership is rooted in characteristics of the leader.

Rise of alternative theories
In the late 1940s and early 1950s, however, a series of qualitative reviews of these studies (e.g., Bird, 1940; Stogdill, 1948; Mann, 1959) prompted researchers to take a drastically different view of the driving forces behind leadership. In reviewing the extant literature, Stogdill and Mann found that while some traits were common across a number of studies, the overall evidence suggested that persons who are leaders in one situation may not necessarily be leaders in other situations. Subsequently, leadership was no longer characterized as an enduring individual trait, as situational approaches (see alternative leadership theories below) posited that individuals can be effective in certain situations, but not others. This approach dominated much of the leadership theory and research for the next few decades.
