 The Goths were also accepted into the empire as "foederati"; however, they rebelled later that year and defeated the Romans at the Battle of Adrianople.The heavy losses that the Roman military suffered during this defeat ironically forced the Roman Empire to rely still further on such "foederati" troops to supplement its forces.In 382, the practice was radically extended when federated troops were signed up "en masse" as allied contingents of "laeti" and "foederatii" troops separate from existing Roman units.
