Ancient/Classical History/Collapse of the Roman Empire
What became of the Roman people in the years following the fall of Rome in A.D. 476? Did they flee? Did they die out? Were they assimilated into other cultures or did they disperse to other parts of Europe? Thank-you for taking the time to answer this question.
in the years following the fall of Western Roman Empire in A.D. 476 when Rome lost its role of capital city of all the Roman Empire the Roman people did not flee nor die out.
They continued living in their town, if you refers only to the inhabitants of Rome and its surroundings, as well as the inhabitants of all Italy, who continued to live in their own towns, though standard of living had become less safe from risk, since Roman military control and rule did not exist any more.
Moreover the Roman people as well as the inhabitants of all Italy did not disperse to other parts of Europe, but remained where they had lived till then, though Italy was subject to many barbarian invasions (the Ostrogoths in 493 AD, the Lombards in 568 AD, the Franks in 772 AD, the Normans in Southern Italy during the 11th century), while the pope ruled over Rome and part of central Italy, because of lack of a civil / military authority.
As for your last question , i.e. “were they assimilated into other cultures?”, I have to tell you that such an assimilation occurred in the opposite direction, since it happened that just the barbarians were assimilated to the Roman and Italic people, whose civilization and culture were definitely superior, so that still today Roman civilization, culture, literature, military power, law, art, architecture, city planning, road system, hydraulics can be traced to Roman origins.
Hope this can be helpful to you, though I had to sum up briefly what happened after the fall of Western Roman Empire in A.D. 476.
