Anecdotal and incidental observations aside, the serious discipline of theorising leadership began in the 19th century.
Early Western history The search for the characteristics or traits of leaders has continued for centuries. 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". A number of works in the 19th century – when the traditional authority of monarchs, lords, and bishops had begun to wane – explored the trait theory at length: especially the writings of
Thomas Carlyle and of
Francis Galton. In
Heroes and Hero Worship (1841), Carlyle identified the talents, skills, and physical characteristics of men who rose to power. Galton's
Hereditary Genius (1869) examined leadership qualities in the families of powerful men. After showing that the numbers of eminent relatives dropped off when his focus moved from first-degree to second-degree relatives, Galton concluded that leadership was inherited.
Cecil Rhodes (1853–1902) believed that public-spirited leadership could be nurtured by identifying young people with "moral force of character and instincts to lead", and educating them in contexts (such as the collegiate environment of the
University of Oxford) that further developed such characteristics. International networks of such leaders could help to promote international understanding and help "render war impossible". This vision of leadership underlay the creation of the
Rhodes Scholarships, which have helped to shape notions of leadership since their creation in 1903.
Rise of alternative theories In the late 1940s and early 1950s, a series of qualitative reviews Additionally, during the 1980s statistical advances allowed researchers to conduct
meta-analyses, in which they could quantitatively analyze and summarize the findings from a wide array of studies. This advent allowed trait theorists to create a comprehensive picture of previous leadership research rather than rely on the qualitative reviews of the past. Equipped with new methods, leadership researchers revealed the following: • Individuals can and do emerge as leaders across a variety of situations and tasks. :*

self-efficacy Specifically,
Stephen Zaccaro noted that trait theories still:
David McClelland, for example, posited that leadership requires a strong personality with a well-developed positive ego. To lead, self-confidence and high self-esteem are useful, perhaps even essential.
Kurt Lewin, Ronald Lipitt, and Ralph White developed in 1939 the seminal work on the influence of leadership styles and performance. The researchers evaluated the performance of groups of eleven-year-old boys under different types of work climate. In each, the leader exercised his influence regarding the type of
group decision making,
praise and
criticism (
feedback), and the management of the group tasks (
project management) according to three styles:
authoritarian,
democratic, and
laissez-faire. In 1945, Ohio State University conducted a study which investigated observable behaviors portrayed by effective leaders. They identified particular behaviors that were reflective of leadership effectiveness. They narrowed their findings to two dimensions. The first dimension, "initiating structure", described how a leader clearly and accurately communicates with the followers, defines goals, and determines how tasks are performed. These are considered "task oriented" behaviors. The second dimension, "consideration", indicates the leader's ability to build an interpersonal relationship with their followers, and to establish a form of mutual trust. These are considered "social oriented" behaviors. The Michigan State Studies, which were conducted in the 1950s, made further investigations and findings that positively correlated behaviors and leadership effectiveness. Although they had similar findings as the Ohio State studies, they also contributed an additional behavior identified in leaders: participative behavior (also called "servant leadership"), or allowing the followers to participate in group decision making and encouraged subordinate input. This entails avoiding controlling types of leadership and allows more personal interactions between leaders and their subordinates. The managerial grid model is also based on a behavioral theory. The model was developed by
Robert Blake and
Jane Mouton in 1964. It suggests five different leadership styles, based on the leaders' concern for people and their concern for goal achievement.
Positive reinforcement B. F. Skinner is the father of
behavior modification and developed the concept of
positive reinforcement. Positive reinforcement occurs when a positive stimulus is presented in response to a behavior, which increases the likelihood of that behavior in the future. The following is an example of how positive reinforcement can be used in a business setting. Assume
praise is a positive reinforcer for a particular employee. This employee does not show up to work on time every day. The manager decides to praise the employee for showing up on time every day the employee actually shows up to work on time. As a result, the employee comes to work on time more often because the employee likes to be praised. In this example, praise (the stimulus) is a positive reinforcer for this employee because the employee arrives at work on time (the behavior) more frequently after being praised for showing up to work on time. Positive reinforcement is a successful technique used by leaders to motivate and attain desired behaviors from subordinates. Organizations such as Frito-Lay, 3M, Goodrich, Michigan Bell, and Emery Air Freight have all used reinforcement to increase productivity. Empirical research covering the last 20 years suggests that applying
reinforcement theory leads to a 17 percent increase in performance. Additionally, many reinforcement techniques such as the use of praise are inexpensive, providing higher performance for lower costs.
Situational and contingency theories Situational theory is another reaction to the trait theory of leadership.
Social scientists argued that history was more than the result of intervention of
great men as
Carlyle suggested.
Herbert Spencer (1884) (and
Karl Marx) said that the times produce the person and not the other way around. academics normalized the descriptive models of leadership climates, defining three leadership styles and identifying which situations each style works better in. The authoritarian leadership style, for example, is approved in periods of crisis but fails to win the "hearts and minds" of followers in day-to-day management; the democratic leadership style is more adequate in situations that require consensus building; finally, the laissez-faire leadership style is appreciated for the degree of freedom it provides, but as the leaders do not "take charge", they can be perceived as a failure in protracted or thorny organizational problems. Theorists defined the style of leadership as contingent to the situation; this is sometimes called
contingency theory. Three contingency leadership theories are the Fiedler contingency model, the Vroom-Yetton decision model, and the path-goal theory. The
Fiedler contingency model bases the leader's effectiveness on what
Fred Fiedler called
situational contingency. This results from the interaction of leadership style and situational favorability (later called
situational control). The theory defines two types of leader: those who tend to accomplish the task by developing good relationships with the group (relationship-oriented), and those who have as their prime concern carrying out the task itself (task-oriented). According to Fiedler, there is no ideal leader. Both task-oriented and relationship-oriented leaders can be effective if their leadership orientation fits the situation. When there is a good leader-member relation, a highly structured task, and high leader position power, the situation is considered a "favorable situation". Fiedler found that task-oriented leaders are more effective in extremely favorable or unfavorable situations, whereas relationship-oriented leaders perform best in situations with intermediate favorability.
Victor Vroom, in collaboration with Phillip Yetton and later with Arthur Jago, developed a
taxonomy for describing leadership situations. They used this in a normative
decision model in which leadership styles were connected to situational variables, defining which approach was more suitable to which situation. This approach supported the idea that a manager could rely on different
group decision making approaches depending on the attributes of each situation. This model was later referred to as situational contingency theory. The
path-goal theory of leadership was developed by Robert House and was based on the
expectancy theory of
Victor Vroom. According to House, "leaders, to be effective, engage in behaviors that complement subordinates' environments and abilities in a manner that compensates for deficiencies and is instrumental to subordinate satisfaction and individual and work unit performance". The theory identifies four leader behaviors,
achievement-oriented,
directive,
participative, and
supportive, that are contingent to environment factors and follower characteristics. In contrast to the
Fiedler contingency model, the path-goal model states that the four leadership behaviors are fluid, and that leaders can adopt any of the four depending on what the situation demands. The path-goal model can be classified both as a
contingency theory, as it depends on the circumstances, and as a
transactional leadership theory, as the theory emphasizes the reciprocity behavior between the leader and the followers.

Ontological-phenomenological model Werner Erhard,
Michael C. Jensen, Steve Zaffron, and Kari Granger described leadership as "an exercise in language that results in the realization of a future that was not going to happen anyway, which future fulfills (or contributes to fulfilling) the concerns of the relevant parties." In this definition leadership concerns the future and includes the fundamental concerns of the relevant parties. This differs from relating to the relevant parties as "followers" and calling up an image of a single leader with others following. Rather, a future that fulfills the fundamental concerns of the relevant parties indicates the future that was not going to happen is not the "idea of the leader", but rather is what emerges from digging deep to find the underlying concerns of those who are impacted by the leadership. == Leadership emergence ==
