Kraków

The city began as a fortified settlement on Wawel Hill around the 8th century. In 1038, it became the seat of Polish monarchs from the Piast dynasty, and subsequently served as the centre of administration under Jagiellonian kings and of the Polish–Lithuanian Commonwealth until the late 16th century, when Sigismund III transferred his royal court to Warsaw. With the emergence of the Second Polish Republic in 1918, Kraków reaffirmed its role as the nucleus of a national spirit. After the invasion of Poland, at the start of World War II, the newly defined Distrikt Krakau became the seat of Nazi Germany's General Government. The Jewish population was forced into the Kraków Ghetto, a walled zone from where they were sent to Nazi extermination camps such as the nearby Auschwitz, and Nazi concentration camps like Płaszów.
