Alexander "the Great" (mass murderer) began his conquests at the age of 20 and had conquered the largest empire the world had ever seen at the age of 26.

Hannibal was in his 20s when he lead the Carthagian campaign against Rome.

Napoleon began at 26 and had conquered half of Europe at 35.

War being a business of old men sending young men to die is a modern thing.
