Lubno (previously also Lubna[1]) is a village within municipal borders of the town of Frýdlant nad Ostravicí in Frýdek-Místek District, Moravian-Silesian Region, Czech Republic.
The village was first mentioned in a written document in 1281[2] in the Latin sentence: magnos a terminis ville, que Lubna dicitur, circa terminos Moravie iusta fluvios Ostraviam.
[1] The village lay on the right bank of the Ostravice river (fluvios Ostraviam), which was in 1261 agreed by a special treaty to be a local border between Upper Silesia and Moravia.
[3] Since then area east of the river belonged politically to the Duchy of Opole and Racibórz and the Castellany of Cieszyn, which was in 1290 formed in the process of feudal fragmentation of Poland into the Duchy of Teschen, ruled by a local branch of Silesian Piast dynasty.
In 1573 it was sold as one of 16 villages and the town of Friedeck and formed a state country split from the Duchy of Teschen.
