<P> Bleda died in 445 , with some historians speculating that his death was at the hands of Attila . With his brother gone , Attila was able to establish undisputed control over his subjects . In 447 , Attila turned the Huns back toward the Eastern Roman Empire once more . His invasion of the Balkans and Thrace was devastating . The Eastern Roman Empire was already beset by internal problems , such as famine and plague , as well as riots and a series of earthquakes in Constantinople itself . A last - minute rebuilding of its walls preserved Constantinople unscathed . Victory over a Roman army left the Huns virtually unchallenged in Eastern Roman lands and they raided as far south as Thermopylae . Only disease forced them to retreat , and the war came to an end in 449 with an agreement in which the Romans agreed to pay Attila an annual tribute of 2100 pounds of gold . Our only first - hand account of conditions among the Huns and of Attila himself is by Priscus , an official in the peace embassy to Attila . </P>
