Hmm, great leaders through history, let's see.
- Alexander the Great
- Gaius Marius
- Augustus
- Charles Martel
- Charlemagne
- Genghis Khan
- Jogaila, I think
- Charles V
- Maurice of Orange
- Gustav Adolphus
- Oliver Cromwell
- Louis XIV (Maybe, a lot of what happened during his reign is directly or indirectly responsible for the French Revolution)
- Frederick the Great
- Napoleon
- Bismarck
These are the ones I can think of, I'm probably forgetting quite a few important ones. Also disregarded military-only leaders, though I would consider quite a few of those as great leaders.
By the end of the 19th century it becomes hard to find leaders who would go into this list; though there were good leaders, things became way more decentralized.
