This list would be an ongoing process. I doubt we could ever agree on who (or why) people should be considered for inclusion.
My own personal priorities would ensure figures who helped create World Powers (Roman, Mongol, British etc) would get top billing.
I feel the religious founders are over-rated. Their original teachings have been changed, twisted, expanded/reduced, re-invented or simply forgotten to fit the political manifesto's of thousands of secular or spiritual world leaders from Constantine to James 1 via Henry VIII.
Just study the reigns of Henry VIII's 3 offspring to understand how members of the same family and generation could be at odds to one another. When one adds the divisions of time and place to the mix the teachings of Christ are all but lost in the smallprint of political control.
