Frýdek (Latin: Fridecca, German: Friedek, Friedeck, Polish: Frydek) was an independent town in Silesia that was joined with the Moravian town of Místek on 1 January 1943 to form the town of Frýdek-Místek.
Frýdek lies on the right bank of the Ostravice River, that was agreed in 1261 by a special treaty between Władysław Opolski, Duke of Opole and Racibórz and Ottokar II of Bohemia to be a local border between their states. In 1290 in the process of feudal fragmentation of Poland the Duchy of Teschen was formed, and the border on the Ostravice was then confirmed in 1297.
The border from the Silesian side was protected by a small gord around which a small town emerged called Jamnice/Jamnica. It could have been first mentioned in a Latin document of Diocese of Wrocław called Liber fundationis episcopatus Vratislaviensis from around 1305 as item in Jannutha. Surely both the town and a gord were later mentioned in 1327 as Jemnicz when Casimir I, Duke of Cieszyn became a vassal of the King of Bohemia. The term oppidum used to describe it in the accompanying document was used in contrary to civitates ruling themselves under German rights of Cieszyn, Bielsko and Fryštát. It probably meant that Jemnicz was ruled under Polish (ducal) traditional rights.
