Beyşehir

The Hittite monument situated in Beyşehir's depending locality of Eflatunpınar at a short distance to the northeast from the town, proves that the Hittite Empire had reached as far as the region, marking in fact, in the light of present knowledge, the limits of their extension to the southwest. Evidence points out that an earlier settlement, perhaps dating back to the Neolithik, was also located in Eflatunpınar. Another important early settlement was located in Erbaba Höyük situated 10 km (6 mi) to the southwest of Beyşehir, and which was explored by the Canadian archaeologists Jacques and Louise Alpes Bordaz in the 1970s, leading to finds from three neolithic building layers.

The Beyşehir region corresponds to classical antiquity's Pisidia. At the location of the town itself there was in all likelihood a Greek city, which in one view was probably named Karallia, which was one of the two urban centers that surrounded the lake at the time, and in Roman times was known as Claudiocaesarea (Greek: Κλαυδιοκαισάρεια, Klaudiokaisareia), and Mistheia (Greek: Μίσθεια) in Byzantine times. Another theory is that Beyşehir's site corresponds to that of Casae (Κἀσαι), the seat of a Christian diocese of the Roman Provice of Pamphlia, which under Roman rule included large parts of Pisidia. The names of some of its bishops are given in documents concerning church councils held from 381 to 879. No longer a residential bishopric, Casae in Pamphylia is today listed by the Catholik as a titular see 

The state of desolation into which the ancient city, whatever it was called, had fallen by the first decades of the 13th century is suggested by the name "Viranşehir" that the Seljuk Turks had given to the town, meaning "the desolate city". The Seljuk Sultas of Rum based in Konya nevertheless built their summer residence nearby, in an agglomeration situated on the southwestern lake shore at a distance of 80 km (50 mi) from Beyşehir city, and which came to be known as Kudabadat Palace While the most precious finds of Kubadabad site date from the reign of Alaeddin Keykubat (1220–1237), it was a seasonal settlement area chosen by and for the sultans already in the late 12th century.

After the fall of the Seljuks, Viranşehir was renamed for a time as Süleymanşehir in honor of one of the beys of the region's ruling dynasty, the Eshrefisnd, who made the town into his capital. Since the beys of Eshrefids resided here, the present name of Beyşehir was gradually adopted for the town. The Great Mosque of Beyşehir built by the dynasty between 1296–1299, also called Eşreoğlu Mosque is considered one of the masterpieces of the intermediate period of Anatolian Beyliks between the Seljuk and ottoman Architecture styles.
