Theory
These emphasis by researches led to theories about leadership. "The first and perhaps most popular, situational theory to be advenced was the? Contingency Theory of Leadership Effectiveness' developed by Fred E.Fielder" (Bedeian, Glueck 504). This teory explauns that group performance is a result of interaction of two factors. These factors are known as leadership style and situational favorableness. According to Fielder, the effectiveness of a leader is determined by the degree of match between a dominant traits of the leader and the favorableness of the situation for the leader. Leaders who describe their preferred coworker in favorable terms. Fiedler also have theory that has some very interesting implications for the management of leaders in organizations there are :

Leadership can be exhibited in a variety of ways and circumstances. Mothers and fathers show leadership in raising their children with good values and encouraging them to develop to their potential. Teachers show it in inspiring students to learn and to develop their intellectual capacity. Health care workers can be leaders and develop services that meet the needs of the communities they serve, or work in collaboration with other organizations to create cost-effective, prevention-oriented programs and services. Many studies have been done and many books and articles have been published on this subject.

1. The favorableness of leadership situations should be assessed using the instuments
2. Candidates for leadership positions should be evaluated
3. If a leader is being sought for a particular leadership position
4. If a leadership situation is being chosen for a particular candidate, a situation should be chosen which matces his/her profile.

Several other implications can be derived from Fiedler's findings. First, it is not accurate to speak of effective and ineffective leaders. Fiedler goes on by suggesting that there are only leader who perform better in some situations, but not all situations. Second almost anyone can be a leader by carefully selecting those situations that match his or her leadership style. Lastly, the effectivness of a leader can be improved by designing the job to fit the manager. For instance, by increasing or dereasing a leader's position power, changing a the structure of a task, or influencing leader-member relations, an organization can alter a situation to better fit a leader's style.

Albert Einstein once said " We shpuld take care not to make the intellect our God; it has, of course, powerfull muscles but no personality. It can't lead; it can only serve."

Leaders know and scince has discovered emotionality's depper purpose. Emotion is the messenger of love; it is the vehicle that carries every signal from one brimming heart to another.

Leadership happens in a series of interactive conversations that pull people toward becoming comfortable with the language of personal responsibility and commitment. That is why leadership development is not an event. It is a process of participating in respectful conversations where the leader recognizes his or her own feelings and those of others in building safe and trusting relationships.
