CEVAP:

Around 425 CE, the Huns were ruled by three brothers: Ruas, Mundzuk, and Oktar. Mundzuk’s sons Bleda and Attila took over power around 434. By 441, Attila had gotten rid of his brother and he declared war on the Eastern Roman Empire, the Byzantines. He conquered major cities south of the Danube River and came all the way down to Arcadiopolis (Luleburgaz). The Byzantium Empire was forced to make peace with the Huns, who exacted heavy terms -- including the surrender of most lands conquered by Attila.
