Explanation:
German tribes exerted pressure on the Roman frontier
In the 4th century A.D. most Germanic peoples in Europe were living east of the Rhine and north of the Danube. To the east, north of the Black Sea, were the East Goths (Ostrogoths) and the West Goths (Visigoths). To the west of these tribes and extending over a large area of the Rhine were the Vandals, Lombards, Alemanni, Burgundians, and Franks. In and near present day Denmark lived the Jutes, Angles, and Saxons.
It was mostly "c. The end of the Crusades" that helped to bring about an increase of trade within western Europe during this time, since this period had been previously dominated by mass violence that disrupted trade routes.
