Gaziemir was founded in the 14th century by Umur Beg (Ghazi Umur, called Umur Pasha in Ottoman sources) of the dynasty of the Beylik of Aydin, who had brought and settled Yörük clans from Konya to the region. The first mention in Ottoman records dates from 1530 and the settlement was named Seydiköy in honor of a Yörük chief, Seydi Ahmed, whose tomb still stands. The town's evolution can be traced fairly smoothly through the centuries by means of regular references in Ottoman sources. After the 17th century, in line with the general pace of development in fertile western Anatolian valleys based on olive/figs/raisin/cotton exports and the ensuing population movements from the Aegean Islands, Seydiköy was largely settled by Greeks which came to constitute a large majority as of the second half of the 19th century.
