WHugh IV was King of Cyprus from 31 March 1324 to his abdication, on 24 November 1358 and, nominally, King of Jerusalem, as Hugh II, until his death. The son of Guy, Constable of Cyprus, and Eschiva of Ibelin, Hugh succeeded his father as Constable of Cyprus in 1318, and later succeeded to the throne of Cyprus on the death of his uncle Henry II, since Henry II had no son.

WUmur Ghazi, Ghazi Umur, or Umur The Lion, also known as Umur Pasha was the second Emir of Aydin, on the Aegean cost of Anatolia, from 1334 to 1348. He was famous for his naval expeditions. As a writer, poet and patron of the arts and sciences, Kalila wa-Dimna was first translated to Persian during his reign. Umur was described in an epic chronicle Düstürnâme-i Enverî, written by poet and historian Enveri during the reign of Sultan Mehmed II, as "the 'Lion of God' leading a just and holy war of conquest against the 'miscreants' and infidel Christians". According to an unreliable but colorful source, 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 Ghazi was a loyal ally and friend of Emperor John Cantacuzenus of the Byzantine Empire and provided him with material aid during his military campaigns, especially during the Byzantine civil war of 1341–1347. He apparently sent 380 ships and 28,000 men to aid him in the conflict and besieged the city of Demotika in Thrace, Greece. The emperor John reportedly mourned his death. At the height of its power, the Emirate of Aydin possessed 350 ships and 15,000 men.
WMartino Zaccaria was the Lord of Chios from 1314 to 1329, ruler of several other Aegean islands, and baron of Veligosti–Damala and Chalandritsa in the Principality of Achaea. He distinguished himself in the fight against Turkish corsairs in the Aegean Sea, and received the title of "King and Despot of Asia Minor" from the titular Latin Emperor, Philip II. He was deposed from his rule of Chios by a Byzantine expedition in 1329, and imprisoned in Constantinople until 1337. Martino then returned to Italy, where he was named the Genoese ambassador to the Holy See. In 1343 he was named commander of the Papal squadron in the Smyrniote crusade against Umur Bey, ruler of the Emirate of Aydin, and participated in the storming of Smyrna in October 1344. He was killed, along with several other of the crusade's leaders, in a Turkish attack on 17 January 1345.
