His marriage with Mal Khatun, the daughter of the learned sheikh Edbali, has been surrounded by poetical legend; he married his son Orkhan to the beautiful Greek Nilofer, daughter of the lord of Yar Hissar, whom he carried off from her destined bridegroom on her marriage-day; the fruits of this union were Suleiman Pasha and Murad.
Infirmity had compelled him towards the end of his life to depute the chief command to his younger son Orkhan, by whom in 1326 the conquest of Brusa was at last effected after a long siege.
At his accession Orkhan was practically on the same footing with these, and avoided weakening himself in the struggle for the Seljukian inheritance, preferring at first to consolidate his forces at Brusa.
These acquisitions were made between 1328 and 1338; in the latter year Orkhan achieved his first conquest from Mussulman hands by the capture of Karassi, the pretext being the quarrel for the succession on the death of the prince, Ajlan Bey.
In 1341 he was succeeded by John Palaeologus, a minor; and Cantacuzenus, the mayor of the palace, appealed to Orkhan for assistance to supplant him, giving in marriage to the Ottoman prince his daughter Theodora.
Orkhan lent the desired aid; his son Suleiman Pasha, governor of Karassi, crossed into Europe, crushed Cantacuzenus's enemies, and penetrated as far as the Balkans, returning laden with spoil.
Suleiman Pasha was killed by a fall from his horse near Bulair in 1358; the news so affected his father Orkhan as to cause his death two months later.
Orkhan was succeeded by his son Murad.
The nocturnal expedition across the Hellespont by which Suleiman, the son of Orkhan, won Galipoli and therewith a foothold in Europe for his race, was shared in and celebrated in verse by a Turkish noble or chieftain named Ghazi Fazil.
MURAD surnamed Khudavendighiar (1319-1389), was the son of Orkhan and the Greek princess Nilofer, and succeeded his father in He was the first Turkish monarch to obtain a definite footing in Europe, and his main object throughout his career was to extend the European dominions of Turkey.
