Orchan

Orhan Ghazi (Ottoman Turkish: اورخان غازی; Turkish: Orhan Gazi, also spelled Orkhan, c. 1281 – March 1362) was the second bey of the Ottoman Beylik from 1323/4 to 1362. He was born in Söğüt, as the son of Osman I and Malhun Hatun. In the early stages of his reign, Orhan focused his energies on conquering most of northwestern Anatolia. The majority of these areas were under Byzantine rule and he won his first battle at Pelekanon against the Byzantine Emperor Andronikos III Palaiologos. Orhan also occupied the lands of the Karasids of Balıkesir and the Ahis of Ankara.He wasintelligent,brave and powerful froma very young age just like his parents, Osman Gazi and Malhun Hatun. A series of civil wars surrounding the ascension of the nine-year-old Byzantine emperor John V Palaiologos greatly benefited Orhan. In the Byzantine civil war of 1341–1347, the regent John VI Kantakouzenos married his daughter Theodora to Orhan and employed Ottoman warriors against the rival forces of the empress dowager, allowing them to loot Thrace. In the Byzantine civil war of 1352–1357, Kantakouzenos used Ottoman forces against John V, granting them the use of a European fortress at Çimpe around 1352. A major earthquake devastated Gallipoli (modern Gelibolu) two years later, after which Orhan's son, Süleyman Pasha, occupied the town, giving the Ottomans a strong bridgehead into mainland Europe. According to Muslim scholar Ibn Battuta, Orhan was "the greatest of the Turkmen kings and the richest in wealth, lands, and military forces".
