510s

Britannia

• Battle of Llongborth (possibly Langport or Portsmouth): Budic II, king of Brittany, seeks after the battle refuge at the court of Aergol Lawhir in Dyfed (Wales).

Europe

• King Theodoric the Great razes the Frankish siege at Arles; the city is heroically defended by its inhabitants, assisted by the Ostrogothic general Theudis. The Ostrogoths overrun Provence (Southern Gaul) and consolidate their gains in the region.
• Theodoric the Great appoints his friend Anicius Manlius Severinus Boethius, Roman philosopher, to the rank of consul of the Ostrogothic Kingdom.

Persian Empire

• The Sasanian Persians conquer the independent kingdom of Caucasian Albania, a state converted to Christianity in the 4th century by Armenian missionaries (approximate date).
