Umur Beg or Ghazi Umur[1] (Modern Turkish: Aydınoğlu Umur Bey, 1309 ?- 1348), also known as Umur Pasha[1] was the Emir of Aydin from 1334 to 1348. Umur was described in a chronicle Düstürnâme-i Enverî, which was written by Enverî during the reign of Mehmed II, as the "Lion of God" leading just and holy war of conquest against the "miscreants" and infidel Christian.[1] However, western sources paint a far less heroic image - two Venetian ambassadors remarked that he was immensely fat with a stomach, "like a wine casket". They had found him wearing silks, drinking almond milk and eating eggs with spices from a golden spoon. Umur was a loyal ally and friend of John Cantacuzenus, and provided him with material aid during his military campaigns, especially during the Byzantine civil war of 1341–1347. At the height of its power, his principality possessed 350 ships and 15,000 men.
His preying on Christian shipping led to the declaration of a Crusade against him by Pope Clement VI in 1343. In 1348, his fleet was destroyed by an allied fleet from Venice, the Knights of Rhodes and Cyprus, and Umur himself was killed in battle.
