Ranking history's kings pits raw conquest against lasting institutions, decisive leadership against cultural flourishing, and personal ambition against stable governance. The stakes are how we measure influence that still shapes borders, laws, and languages today. Compare the candidates and vote.
What counts: Best means greatest net historical impact through conquest, administration, and legacy; reign lengths and ratings are approximate round figures.

This is the most honest version of this ranking I've seen anywhere. The pros and cons are fair.
Came for the argument, stayed for the comparison grid. The numbers settle half the fights here.
Missing a few names that belong in the top ten, but the top three is basically right.
Wild that Alexander the Great is winning this. Scroll down — the real answer is further down the board.
Voted, but this order is going to look very different in a month once more people find it.
Alexander the Great at the top is the correct call and I'll die on this hill.
