Battle of the Catalaunian Plains
The Scirii were mentioned already in the late 3rd century BC as participants in a raid on the city of Olbia near modern-day Odessa. In the late 4th century they lived somewhere north of the Black Sea and Lower Danube in the vicinity of the Goths. By the early 5th century, the Scirii had been subdued by the Huns, whom they fought under at the Battle of the Catalaunian Plains in 451 AD.
