To promote trade, the Elbe Valley railway line was completed in 1851, which stimulated development along the left bank of the river. Soon, neighbouring Bodenbach (Podmokly) grew bigger than Tetschen and received town privileges in 1901. Upon the forced 1938 Munich Agreement, both towns were annexed by Nazi Germany, incorporated into the "Reichsgau Sudetenland", and merged in 1942. After World War II, the ethnic German population was displaced and expelled under terms of the 1945 Potsdam Agreement and the Beneš decrees.
