Dreher said "The massive migration of barbarians into the Roman Empire, in the 4th through 6th centuries, changed European civilization permanently. They caused the fall of the Western Roman Empire, and centuries later, the rise of a new civilization there, based on the descendants of old Roman stock and Christianized Germanic tribes. Will the latter-day descendants of those Europeans be able to hold back the “barbarian invasions” from Africa in the 21st century? Or will they have to do as the Romans did and absorb the strangers, and, over centuries, create a new civilization? These are the stakes".
Is it true that the Barbarian invasions were as bad as people like Dreher say they are or is there more to the story?
Edit: I accidentally deleted another portion of my post. What I said was I kept seeing the Barbarian invasions of Rome being used as a comparison for modern migrations, but this doesn't particularly make any sense to me. The comparison seems very forced for one, and the people who make tend to ignore a lot of the nuances of the modern migration situation and the nuances of previous barbarian invaders.
More can be (has been, will be) written on the subject of the so-called "The Fall of the Roman Empire".
One previous discussion of note is 'How accurate is the popular view that "uncontrolled immigration led to the fall of the Roman Empire"?' by /u/Iguana_on_a_stick and /u/shlin28 . There's also a link to followon discussion in the Sunday Digest link there. Despite the post title, it wasn't just about immigration issues, but a large-scale look at some recent historiography of what happened to the Roman Empire around the 400s.
The bigger section is at 'Late Antiquity/Early Medieval/"Dark Ages"'. Please note the first title: "Why does the concept of the end of the Roman Empire in 476 CE persist?" (replies mostly by /u/bitparity ). An even more telling discussion title from elsewhere: "Did Rome Actually Fall?" . There yodatsracist provided a lot of pointers to previous discussions along those lines.
This is not to discourage discussion. More questions, data, and debate are welcome.
