What is your definition of "large areas"? The Inuit conquered over 6000 kilometers of land, and still own much of it themselves.
I think the key word is centralized. Also, 6000 sq km is about the size of a tile in civ4 so It's probably a hex in civ5.
I do not think you know how big a kilometer is if you think that 6000 kilometers makes one hex tile in Civilization V.
Deanej is absolutely right, 6000 sqr kilometers can easily be the size of a tile on most maps - depending on exact map size of course. Less than 80*80 kms
Of course it's easy to guess that you wanted to talk about the territory being more than 6000 kms wide or long.
But when you say something like "conquered over 6000 kms of land", it sort of implies that you are talking about territory, not distance.
