The Goths were briefly reunited under one crown in the early 6th century under Theodoric, who became regent of the Visigothic kingdom following the death of Alaric II at the Battle of Vouillé in 507. Shortly after Theodoric's death, the country was invaded by the Eastern Roman Empire in the Gothic War, which severely devastated and depopulated the Italian peninsula. The Ostrogoths made a brief resurgence under their king Totila, who was, however, killed at the Battle of Taginae in 552. After the last stand of the Ostrogothic king Teia at the Battle of Mons Lactarius in 553, Ostrogothic resistance ended, and the remaining Goths in Italy were assimilated by the Lombards, another Germanic tribe, who invaded Italy and founded the Kingdom of the Lombards in 567.
