I think that's too broad of a topic - I might be able to pick standout politicians from specific time periods, but "history" is just too general. I mean, can you really compare Alexander the Great to Adolf Hitler, Charlemagne to Otto von Bismarck or Julius Caesar to Ronald Reagan? I dunno, I think that there are certainly politicians and leaders that have had more influence and stand out from the crowd more than others, but I don't think I can pick any one person and say that they are historically "greater" than any other person.
Also, politician is a very elastic definition. Adolph Hitler was as much a politician as, say, Henry Clay or even a current senator. Specify what you mean, WilliamPennHigh. Then we'll give ya some feedback.
this topic is too broad and general.
