LEADERSHIP THEORIES REVIEW

Through years many theories, definitions and classifications about leadership have been developed and can be found in the contemporary literature. Despite the fact that volumes of writings about leadership exist in global literature still it is considered a debated subject since the leadership content remain inconsistent and unclear. In addition, researchers in an effort to define and classify leadership have concluded that it is a complex, flexible and multidimensional phenomenon which requires plenty light to be shed on it. The most prominent theories that emerged during 20th century and will be analysed in chronological order constitute of the Great Man theory, Trait theory, Contingency and Behavioral theory. The purpose of the present paper is to examine the wider context of leadership and its effectiveness towards improving, through organizational changes, the public sector in times of crisis. It can be considered as an additional conceptual approach to the existing literature.
