Leadership is a hot topic. But what approaches, representatives, and theories lie behind it? What is current, what belongs to classical modernity, and what is outdated? The five-part reader "Leadership" provides a comprehensive overview of approaches, developments, and trends in leadership and management, serving as a guide to better position your own perspective on leadership with references. Our goal is to support you in your daily work with executives, colleagues, or employees and to enrich the discourse on leadership in Germany in a factual manner. Part 1 "Initial Approaches" describes the oldest leadership theories that place the leader at the center of interest, as well as the resulting leadership style approaches and theories of situational leadership. Additionally, the Harzburger Model is discussed.
