Sibiu was founded by Transylvanian Saxons – ethnic Germans who were resettled in the region in order to defend its borders, mainly from the Ottoman enemy.
Up until 1941, Sibiu had a mixed German-Romanian population, with a small Hungarian minority. A part of the Germans were “relocated” by the Nazis after the secret 1939 Molotov pact through which Hitler and Stalin divided Romania and the Soviets were allowed invasion of Romanian territories. The resettlement called “Heim ins Reich'” (Home to the Reich) was in fact a safety measure against the secret Soviet invasion. After World War II, a forced expulsion of the remaining German population occurred, policy created by the Allies and applied all throughout Eastern Europe.
Today, Sibiu has a Romanian population with a Hungarian minority.
