Just a brief note. Just a little Dead White Male history:
In the summer and fall of 376, tens of thousands of displaced Goths and other tribes arrived on the Danube River, on the border of the Roman Empire, requesting asylum from the Huns. Fritigern, a leader of the Thervingi, appealed to the Roman emperor Valens to be allowed to settle with his people on the south bank of the Danube, where they hoped to find refuge from the Huns, who lacked the ability to cross the wide river in force. Valens permitted this, and even helped the Goths cross the river, probably at the fortress of Durostorum (modern Silistra), Bulgaria.
Valens promised the Goths farming land, grain rations, and protection under the Roman armies as foederati. His major reasons for quickly accepting the Goths into Roman territory were to increase the size of his army, and to gain a new tax base to increase his treasury.
To outline what happened over the course of the next six years would be racist (of course), and it is left to the reader to commit that crimethink for himself.
