Classification of leadership theories in organizational behavior?

There are many theories about leadership, and as management theory has evolved, there have been four broad theoretical schools of thought on leadership theory: early trait and behavioral theories, more recent contingency theories, and current leadership style theories. According to the chronological order, at the end of the 1940s, the early stage of the emergence of leadership theories, researchers were mainly engaged in the study of leadership trait theories, whose core view is that leadership ability is innate; from the end of the 1940s to the end of the 1960s, the main research was conducted on leadership behavioral theories, whose core view is that the leadership effectiveness is related to the leadership behaviors and leadership styles; from the end of the 1960s to the early 1980s, the theory of leadership power change appeared, and the theory of leadership style is the most recent. From the late 1960s to the early 1980s, the theory of leadership change appeared, and its core view is that effective leadership is affected by different scenarios; from the early 1980s to the present, a large number of studies on the theory of leadership style appeared, and its main view is that effective leadership needs to provide vision, inspiration and focus on action.
