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> <P> Throughout their raids on the Eastern Roman Empire, the Huns had maintained good relations with the Western Empire, and in particular with Flavius Aetius, a powerful Roman general (sometimes even referred to as the de facto ruler of the Western Empire) who in his youth had spent time as a hostage with the Huns . However, this all changed in 450 when Honoria, sister of the Western Roman Emperor Valentinian III, sent Attila a ring and requested his help to escape her betrothal to a senator . Attila claimed her as his bride and half the Western Roman Empire as dowry . Additionally, a dispute arose between Attila and Aetius about the rightful heir to a king of the Salian Franks . Finally, Attila's ability to distribute treasure to favoured followers was an important support to his power, and the repeated extortion from the Eastern Roman Empire had left it with little to plunder . </P>
