No one is "civilized". "Civilization" is the process of developing a more productive, secure, compassionate, society. Many cultures started and spread the process, each adding different techniques and ideas into their own experiments. Africa, Sumeria, Egypt, India, and China, were among the first. Being "civilized" is coercion to look and act like a certain culture or class, absorption or assimilation into the dominant collective hierarchy.
A leader compassionately guides, nurtures, protects, and prods those for whom they are responsible. A tyrant forces to them to behave as desired. A leader is an exemplar in action, not a saint.
A compassionate leader is a real leader.
