Migration in the Roman EmpireDuring the migration period the Roman Empire was invaded by many refugees at different times and for different reasons and purposes. The migration period was between 300 and 700 AD The Roman Empire was invaded by many groups of people such as Visigoths, Celts and others. The entire group of migrations that invaded Rome led the empire to its fall. As many know, the Roman Empire was very powerful and strong, but they also felt pressured by other groups of people who invaded them. After all the struggles the Roman Empire faced due to immigrants, it was vulnerable in terms of military strength. The main questions many may ask you are: who migrated to the Roman Empire and what was their purpose in migrating there. The first migration that invaded the Roman Empire was that of the Visigoths. The Visigoths were people from Germany, they were a western tribe that settled in the western part of the Black Sea. They invaded Rome during the Migration Era and migrated to the Roman Empire in 376. When the Visigoths invaded Rome they wanted to defend the Danube frontier. Instead they invaded Italy and sacked Rome in 410. Even when the Visigoths invaded Rome, the Romans were not prepared for the invasion of this large group of people. The Visigoths lived in the south of the Danube because the Romans allowed them to settle there. The Romans called for the Visigoths and for this they attacked the Roman Empire in 378 AD, and two thirds of the Romans were killed, their emperor named Valens was also killed but his body was never found. After this invasion the relationship with the neighbors changed a lot. By 395 AD the Visigoths became very agitated and had a new ruler named Alaric. Alaric wants more from the Romans, such as more funds, better territory. After a long journey through Europe in 401 the Visigoths arrived in Rome. When they left Rome they did not destroy the city but were loaded with loot. The Visigoths were the first enemy to enter Rome and remained there for eight centuries exactly when the Celts arrived in Rome in 390 BC. The next group of migrants, that invaded the Roman Empire where the Celts. The Celts were a diverse tribe because their culture was formed during the Iron Age. They crossed the Alps towards the south and in 390 reached Rome and even attacked it.
