Overview

The Aydinids (Aydınoğulları), Beylik of Aydın, were a western Anatolian principality famous for seaborne raiding. Its capital was Birgi, with the great ports of Ayasoluk (Selçuk, near ancient Ephesus) and Smyrna (İzmir). It began as a vassal of the Germiyanids; the eponymous founder Aydınoğlu Mehmed Bey had been a Germiyanid commander. Conventional dates are c. 1300/1308–1425/1426. Mehmed Bey (r. 1308–1334) extended the beylik into former Byzantine lands to the Aegean coast.

Decline and legacy

Its most celebrated ruler was Umur Bey (Umur Ghazi, "Umur the Lion," r. 1334–1348), who built a formidable fleet and conducted repeated naval expeditions across the Aegean, into Thrace, the Morea, and the Aegean islands, often in alliance with the Byzantine claimant John VI Kantakouzenos during the Byzantine civil war of 1341–1347. His raids provoked the Latin Smyrniote Crusades; a crusading fleet burned the Aydinid fleet and took the harbour fortress of Smyrna, and Umur was killed attempting to retake it in 1348. The beylik declined thereafter; Bayezid I annexed it before 1402, Timur restored it, and the last ruler, İzmiroğlu Cüneyd (Junayd) Bey (r. 1405–1425/1426), resisted the Ottomans until Murad II finally annexed Aydın in 1425/1426. Aydın's naval tradition, like that of Karesi and Menteşe, fed directly into Ottoman sea power.
