In ancient civilizations, leaders were often seen as stewards of their communities. In ancient Greece, the philosopher Socrates emphasized the importance of service to the community, arguing that a good leader must prioritize the welfare of others. His student, Plato, extended this idea by introducing the concept of the "philosopher-king," a ruler who embodies wisdom and moral integrity. This early recognition of the leader's duty to serve laid the groundwork for future concepts of service leadership.
