Attila ( ə-TIL-ə or AT-il-ə; c. 406 – 453), frequently called Attila the Hun, was the ruler of the Huns from 434 until his death in early 453. He was also the leader of an empire consisting of Huns, Ostrogoths, Alans, and Gepids, among others, in Central and Eastern Europe.
As nephews to Rugila, Attila and his elder brother Bleda succeeded him to the throne in 435, ruling jointly until the death of Bleda in 445. During his reign, Attila was one of the most feared enemies of the Western and Eastern Roman Empires. He crossed the Danube twice and plundered the Balkans but was unable to take Constantinople. In 441, he led an invasion of the Eastern Roman (Byzantine) Empire, the success of which emboldened him to invade the West.
