Military history has a few figures who didn't just win battles or campaigns, but changed the world and the destiny of their nations. From the earliest world conquerors, men who laid waste to the entire known world; to modern tactical geniuses using weapons that previous generations only dreamed of, these are the best military leaders, those who were known, feared and respected by both their people and their opponents.
Some of the best army generals in the world and best international army leaders are known even by people who know little else about military history. Others are less well-known but no less important. And every country in history has their own heroes, leaders who commanded forces in the battles that shaped their destiny. This list is far from comprehensive, and can never be, but attempts to find a cross-section of legendary warrior-kings, great strategists, modern innovators, and legendary blood and guts men and women who personally fought in combat.
Vote up the greatest military leaders below, and vote down the ones who might be overrated. Be sure to add other famous military leaders who aren't already listed to make the debate even more complete.
