Sonderaktion Krakau
Operation Sonderaktion Krakau was a brutal action carried out by Nazi Germany on November 6, 1939, in Kraków, during which 183 academics were arrested, mainly from the Jagiellonian University. This event was part of the occupier's broader plan aimed at destroying Polish intelligentsia and culture. Most of the arrested were sent to the Sachsenhausen concentration camp, where 15 professors lost their lives.
