Recent approach to complexity theory (Mary Uhl-Bien, Russ Marion & Bill McKelve, 2007) of leadership attempt to move toward “a new understanding of what leadership is, in a post-industrial school of leadership” by developing a model of leadership based in complexity science in bureaucratic forms of organizing (Mary Uhl-Bien, Russ Marion, 2009). This study has tried to drop the old paradigm of “Reductionist Thinking” to reach to a holistic view and model which can be offered by Complexity Theory and consequently succeeded here to offer: 1. A broad solution which is embedded in Complexity science. 2. General Model of Leadership as a Complex Adaptive System (CAS) 3. Understand and Explain how attractors affects CAS of leadership 4. Look at Leaders Brain instead of Behavior 5. An start to Complex Plane (called here also phase space) of the complex function to simulate emerged system of Leadership.
