The throughputs of Management sciences have always been in the middle of interest for its 105 years long history. Analysing the management styles is a prospering and actual scientific approach of leadership research. In the following, I present the throughputs of the researches which are applying this approach: I introduce both the „classical”management style models and the new ones. As for„classical”models, I introduce the decision-making oriented typologies, the personality oriented typologies and the situational leadership theories. By „new”theories I introduce the feminin and masculin management styles, the transactional and the transformational leadership and the participative management style. In the article I summarize the internal and external factors that influence the management style, and the same time introduce the outcomes of researches studying the topic.
