Gdansk is a city in Poland in Europe’s Baltic region. The city sits on the mouth of the Vistula River at the Baltic Sea. The big industry of Gdansk is shipbuilding and shipping, and Gdansk has two major ports for these and other industrial activities.
Gdansk was the Polish city that Adolph Hitler demanded be handed over to Germany. When Poland refused, Hitler invaded Poland and this sparked off World War II. The invasion of Poland began on September 1st, 1939, and Gdansk was returned to Poland again in March of 1945. It was in Gdansk where Lech Walesa raised the flame that signalled the collapse of the Soviet Union and the end of communism.
