Laonikos Chalkokondyles also wrote that Itéas Kómi (Ἰταίας Κώμη) was an older Greek name for Söğüt, but since Greek "itéa" (Ιταία) and Turkish söğüt both mean "willow", Klaus Belke considers this "more of a learned translation" than a genuine older name for the town.

[6] Ertuğrul and his tribe (allegedly part of the Kayi tribe/branch of the Oghuz Turks who invaded Anatolia in the 12th and 13th centuries) migrated and settled there during the Mongol invasion after the Battle of Köse Dağ.

The kaza centre included present-day districts of İnhisar, İnönü, Mihalgazi, Sarıcakaya and Yenipazar, central and eastern parts of Bozüyük and some villages of Nallıhan and Tepebaşı before World War I. Söğüt was occupied three times by the Greek Army during the Turkish War of Independence: 8–11 January 1921, 24 March-21 April 1921 and 12 July 1921 – 6 September 1922.

Today Söğüt is a small town in the humid river valley of Bilecik Province in Turkey.

Turkish history and life-size statues of the Ottoman sultans are exhibited in the Söğüt Ethnographical Museum.
