The conference met on the right bank of the Danube within the Empire, that is near the Roman town of Margus or Margum, a city of Moesia, where the Danube and the Morava meet. The place was known as the _Margum planum_ on account of the character of the country, and was famous as the spot where Diocletian had defeated Carinus.[7] The Byzantine historian Priscus has left us an account of this strange meeting. The Huns it seems came on horseback and as they refused to dismount the Roman ambassadors also remained on their horses. It was thus they heard the arrogant demands of the Hunnish kings: the denunciation by Theodosius of his alliance with the Barbarians of the Danube, the expulsion of all the Huns serving in the Imperial armies or settled within the Empire, an undertaking not to assist any Barbarian people at war with the Huns, and the payment by the Empire as tribute, _tributi nomine_, of seven hundred pounds’ weight of gold instead of the three hundred and fifty given hitherto. To all these demands the ambassadors were forced to agree as Attila insisted either upon their acceptance or upon war, and Theodosius preferred any humiliation to war. The famous conference of Margus was thus a complete victory for the Huns, a victory Attila never forgot. That Theodosius was ready to accept any terms which Attila might insist upon is proved by the fact that he immediately delivered up to him his two guests, young princes of the Huns, and made no protest when Attila crucified them before the eyes of his ambassadors.
