This practical handbook is a translation of the German reference work on leadership, aimed at those interested in the practical application of leadership knowledge. This implementation knowledge is particularly important for current and aspiring leaders, as well as trainers, consultants, coaches, HR developers, and students in psychology and social sciences. The clearly written contributions do not require specific prior knowledge and provide an excellent overview of the current state of research.The focus is on the practical application of knowledge, with contributions from recognized experts in the German-speaking world.

In approximately 50 chapters, the latest insights into modern leadership theories (e.g., ethical or authentic leadership), health-promoting leadership, and the management of (age) diverse groups are presented in a practical manner. Each contribution is uniformly structured and easily accessible through a brief summary, starting with a case study that addresses specific issues. Depending on the topic, the contributions also include ready-to-use checklists, guidelines, training concepts, or tools, making them immediately applicable in practice.

This reference book can be useful for managers and people interested in leadership from all over the world.
