(Ermenice) 1199 tarihli Kilikya Beyleri protokolü; akt. Smpad Sbarabed vekâyinamesi [1274'ten önce]; ed. Dulaurier, Recueil des Historiens des Croisades I, Paris 1869.
The Manavgat River likely derives its name from the town of Manava, mentioned since the 6th century, located in the present-day Akseki-Kepez area. The indigenous people of the region are referred to as Manavlu, and it is said that they "came from the Akseki side." The meaning of the +gat suffix, seen in the earliest Armenian source from 1199, is unclear. Manav-ked ("Manav River") can be considered. During the Ottoman period, the western bank of the river was the Manavgat district/sub-district, while the eastern bank was the Düşenbe district. The current district center was established at the Pazarcık location by the Manavgat bridge.
