well i dunno for a fact, but i'd say probably Romans coz not only did they invent new stuff, architecture n literature & all those other -atures, they refined what they learnt [ok, what they basically stole] from the Greeks. Romans came off as more... acquisitive, to me, they thought they knew what was best for the world and damnit they'd crusade if they had to.... sorry no specifics
add: you can borrow em from the girl above me though....
