Fritigern was a Terwingian reik and general who led the majority of the Terwingen into the Roman Empire in 376 after the Huns crushed the Gothic Empire on the Danube. Fritigern's Kuni was located west of the Pruth, and he was an Arian and an opponent of Athanaric, who held the office of judge before the Hun invasion in 375. Emperor Valens granted the Visigoths settlement space in Thrace and Smyrna, but poor provisioning soon led to the Gothic War. Fritigern defeated Valens in the Battle of Adrianople on August 9, 378, a disaster for the Romans that destroyed part of their eastern field army. The Goths were unable to take advantage of this victory. Afterwards, there were fighting activities with the Romans under Theodosius the First, who concluded a treaty with the Goths in 382. Fritigern's name no longer appears there, indicating that he may have died or no longer played a role.
It is unclear what Fritigern's Gothic name was, but he is sometimes equated with Friþareiks mentioned in the Gothic calendar fragment. According to this, his name would correspond to the German name Friedrich, and his memorial day was October 23. In the 19th century, a memorial plaque (No. 7) was erected for Friediger in the Valhalla memorial.
