The celebrated date of the village of Řeka's foundation is 1644. The village began life by breaking away from Smilovice and Guty. The new village was initially called Řeka Smilovská. Smilovice was first recorded as a farm in 1448, confiscated by the Těšín Chamber in 1592. Guty dates to 1305. Řeka like every mountain village originated with the joining of already existing dispersed mountain clearings and mountain farms. Even more small farmers settled in the newly created village during subsequent years. The Wallachian element played its part in the formation of farms at Řeka, or more specifically, in the building of the so-called salaše (Alpine dairy huts). The Wallachians slowly migrated to us during several centuries from Wallachia, today's Romania. In this way, for some centuries of a continuing migration, they gradually assimilated significant aspects of Ukrainian, Silesian, Polish and, finally, Czech language and culture - the greatest influences being Silesian and Moravian.
