What were the motivating factors that contributed to
imperialism and colonization?

the major factors that contributed to the growth of American imperialism were desire for military strength, thirst for new markets, and belief in cultural superiority.

well this is going to be a long answer lol ok so the visigoths were a branch of the goths who frequently raided rome, uh the hunas attacked the guptas a lot and weakened them, uuhm of course the romans used math and science in there every day lives i mean they had a whole empire to run, and rome was split into east and west by a general named diocletian. hope this you! : )
