Komsomolsk-on-Amur
The government of the Russian SFSR announced plans in 1931 to build a shipyard on the Amur at the modern site of Komsomolsk. Construction began in 1932. The town was mainly built using volunteer labor from the Communist youth organization Komsomol. This is how the town received the name Komsomolsk. However, the construction of the town was helped by the use of penal labour from the prison camps in the area. The suffix on Amur was added to differentiate from other towns with the same name.
