Why did the Ostrogoths and Visigoths follow Roman customs? Please help I’ve been stuck on this for hours

Their mistreatment at the hands of Roman provincial governors would lead to the First Gothic War and the pivotal Battle of Adrianople (378 CE) in which Rome was defeated by the Goths under Fritigern. The Visigoths would further impact Rome when their king Alaric I (r. 395-410 CE) sacked the city in 410 CE

Explanation:

Why did the Ostrogoths and Visigoths follow Roman customs?

Because the Goths were a nomadic Germanic people who fought against Roman rule in the late 300s and early 400s A.D., helping to bring about the downfall of the Roman Empire, which had controlled much of Europe for centuries. The ascendancy of the Goths is said to have marked the beginning of the medieval period in Europe.
