History
Řeka was founded in 1644 was formed by the separation from Smilovice and Guty, and originally named Řeka smilovská. It belonged then to the Duchy of Teschen. The village was established as a typical mountain settlement by associating already existing scattered mountain pastures and mountain farms. In the following years, other small farmers settled in the newly formed village. The main source of livelihood of the inhabitants was mountain farming.[2]
After Revolutions of 1848 in the Austrian Empire a modern municipal division was introduced in the re-established Austrian Silesia. The village as a municipality was subscribed to the political and legal district of Cieszyn.
