THE GOTHS
 

The Goths came down from Scandinavia and gained momentum as they went.

In the 3rd century AD, the Goths split into East Goths and West Goths, or Visigoths and Ostrogoths.

Alaric I was king of the Visigoths and so was Theodoric I, who was one of the few who managed to defeat Attila in battle.

253-260 - The Franks and Alemanni invade Gaul, Spain, and Africa.
The Goths attack Asia Minor and Greece. The Persians conquer
Armenia. Their king, Sapor, defeats the Roman emperor Valerian,
and takes him prisoner. General distress of the Roman empire.

AD 260 - The Goths invade the Roman provinces. The emperor Decius is defeated and slain by them.

Fritigern was a commander of the Visigoths who led his troops to victory at the Battle of Adrianople in 378, in which Roman Emperor Valens got killed.

And then there was Alaric, chief of the Visigoths from 395, and leader of the army that sacked Rome in August 410, an event that symbolized the fall of the Western Roman Empire.

412 - The Goths march into Gaul, and in 414 into Spain, which had
been already invaded by hosts of Vandals, Suevi, Alani, and other
Germanic nations.

Britain is formally abandoned by the Roman emperor of the West.
