Perateia

Perateia (beyond the sea) was the overseas territory of the Empire of Trebizond. It comprised Crimean cities of Cherson, Kerch and their hinterlands. In 1223 the Seljuks Turks raided Perateia's coasts, and built the fortress of Sudak to try and channel the Crimean trade to Trebizond into Seljuk-held Sinope.
