Leadership has come to the fore with different characteristics throughout civilizations as a phenomenon independent of cultural, geographical and ethnic characteristics that all societies experience in common. The achievements of important figures in history with their leadership characteristics in civilizations such as Ancient Greece, Egypt and China have become epic. The historical leadership records that have continued over these centuries have caused people to think, question and do different research on the characteristics of leaders. Especially in the twenty-first century, it is seen that leadership and leader effectiveness have become an important issue in scientific research. Although it is discussed from many different perspectives and paradigms, such as the leader's different dimensions and situations such as behaviors, characteristics, skills and power sources that reinforce his influence on followers and group goals, it is difficult to say that changing situations and information can be adequately evaluated.
