Identify one factor that contributed to the rise of barbarian invasions of the roman empire pl

The most direct hypothesis for Western Rome's fall was a string of military misfortunes maintained against outside powers.
Rome had gone head to head with Germanic tribes for a considerable length of time, however by the 300s "Barbarian" like the Goths had encroached past the Realm's borders. The Romans weathered a Germanic uprising in the late fourth century, yet in 410 the Visigoth Lord Alaric effectively sacked the city of Rome. The Empire spent the following quite a few years under steady risk before the City was attacked again in 455, this time by the Vandals. Eventually, in 476, the Germanic chief Odoacer organized a revolt and dismissed the Sovereign Romulus Augustulus. From that point on, no Roman sovereign could until the end of time govern from a post in Italy, driving many to cite 476 as the year the Western Realm suffered its final knockout.
