What person/country came closest to conquering the world?
depends on what time frame - How much of the world?
well i think that is an opinion, but I would say Hitler with Germany, because he had conquered most of Europe and some of Africa and Asia....
greece alexander the great i think..
Russian Empire (soviet era)
Actually it hasn't happened yet, Phlorence tells me she's gonna successfully take over the world. Not sure when though. I hope I'm on her good side...
Rome, back in the day romans were feared by all.
Napoleon I think, and Alexander the Great.
Attila the hun
I think Japan and Germany teamed up to try to take over the world. They ended up losing. :)
Alexander of Macedon (a.k.a. Alexander the Great) conquered all the known world in his day, that is at least all the lands that were considered civilized and worth taking.
Portuguese. The sun never set on their empire. The owned territory all over the globe.
