What is the theory that suggests that leaders are born not made?

The Great Man Theory by Thomas Carlyle assumes that the capacity for leadership is inherent—that great leaders are born, not made. This theory often portray great leaders as heroic, mythic, and destined to rise to leadership when needed. The term "Great Man" was used because, at the time, leadership was thought of primarily as a male quality, especially in terms of military leadership.

Such theories suggest that people cannot really learn how to become strong leaders. It's either something you are born with or born without.
