In the Taurus Mountains, on the northern limits of Lesser Armenia, and to the south-east of Karamania, the Turcoman tribes through whom Marco Polo passed seemed to him to enjoy an independent existence. Up to the time of Murad I, they formed no state, but between 1373 and 1375 the family of Ramazan took the chieftainship. When the Mamelukes destroyed the Armenian kingdom (1375), the Ben-Ramazan dynasty established itself at Adana, on the Sarus, in the fertile Cilician plain.[740] The Ben-Ramazan emirs managed to keep from being absorbed either by the Karamanians or the Egyptians. After the complete subjugation of Karamania by the Osmanlis, they submitted to Selim I about 1510, under the stipulation, however, that the emir, Piri pasha, should hold office for life as vali of Adana and Sis. Sis was frequently coupled with Adana in the title of the Ben-Ramazan. AÏDIN (2) Aïdin comprised the greater part of Ionia, with a portion of Lydia, if we take its boundaries to be those of the present vilayet of the same name. It comprised, at the time of its greatest extent, Smyrna, Ephesus, and Tralles. Smyrna was captured by the crusaders in 1344. Ephesus was at times independent under the name of Ayasoluk. Tralles, called Guzel Hissar, and sometimes also Birgui or Berki, was the capital of Aïdin in the time of Orkhan. Later, Ayasoluk, and, last of all, Tira, were the successive capitals. The emirate was founded by Aïdin, a contemporary of Osman, who was succeeded by his son Mohammed about 1330. Ibn Batutah regarded Mohammed as a very powerful prince, who was especially strong on the sea. His eldest son, Omar, who succeeded him in 1341, met death in an unsuccessful attempt to recapture Smyrna in 1348. His relations with Cantacuzenos are given in the chapter on Orkhan. Isaac, fourth of the line, reigned from 1348, until he was dispossessed by Bayezid in 1390. He died in exile at Nicaea. His sons, Isaac II and Omar II, were placed again on the throne in 1403. The line of Aïdin became extinct soon after. A usurper, Djuneïd, Ottoman governor of Smyrna, managed to keep the power until he was assassinated in 1425. It was not until then that Aïdin definitely passed into the hands of the Osmanlis.
