"In the United States, a political party committee is an organization, officially affiliated with a political party and registered with the Federal Elections Commission (FEC), which raises and spends money for political campaigning."

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! : )
