Karviná coal basin and the railway line) and smaller western part of the town, known later as Český Těšín, while Poland received the eastern section with Cieszyn and its historical centre. During interwar period two villages were submerged with Cieszyn: Błogocice (in 1923) and Bobrek (in 1932). Since then, Poland occasionally claimed the Czech section, eventually annexing it in October 1938 after the Munich Agreement. The whole town was annexed by Germany in 1939 as a result of the invasion of Poland. During World War II the city was a part of Nazi Germany. The 1920 borders were restored after the war in 1945. During the German occupation there was a stalag camp in the town, Stalag VIII-D. After World War II, both cities were expanded by joining adjacent villages. Svibice (1947), Dolní Žukov (1960), Horní Žukov, Mistřovice (together with Mosty and Koňákov) and Stanislavice (1975) were amalgamated with Český Těšín, whereas in 1973 Boguszowice, Gułdowy, Kalembice, Krasna, Mnisztwo, Pastwiska and in 1977 Marklowice were amalgamated with Cieszyn.
