A.

Explanation:

On accepting his elevation, he campaigned against Goths and other barbarians who had invaded the Empire. His resources were not sufficient to destroy them or drive them out, which had been Roman policy for centuries in dealing with invaders. By treaty, which followed his indecisive victory at the end of the Gothic War, they were established as foederati, autonomous allies of the Empire, south of the Danube, in Illyricum, within the Empire's borders. They were given lands and allowed to remain under their own leaders, a grave departure from Roman hegemonic ways. This turn away from traditional policies was accommodationist and had enormous consequences for the Western Empire from the beginning of the fifth century, as the Romans found themselves with the impossible task of defending the borders and dealing with unruly federates within. Theodosius I was obliged to fight two destructive civil wars, successively defeating the usurpers Magnus Maximus in 387–388 and Eugenius in 394, though not without material cost to the power of the Empire.
