There are contradictory opinions as to whether the fall of the Western Roman Empire was a result of an increase in migrations, or if both the breakdown of central power and the increased importance of non-Romans created additional internal factors. Migrations, and the use of non-Romans in the military, were known in the periods before and after, and the Eastern Roman Empire adapted and continued to exist until the fall of Constantinople to the Ottomans in 1453. The fall of the Western Roman Empire, although it involved the establishment of competing barbarian kingdoms, was to some extent managed by the Eastern emperors.
