Among the first targeted by the Nazis were the intellectual elite of Poland. German officials wanted to make Kraków culturally German and therefore needed to eliminate any who got in the way of that goal. Nazi leaders hatched a plan called Sonderaktion Krakau, or Special Action Kraków.
Academics and professors of the Jagiellonian University in Kraków, were lured into a false meeting, where they were told they did not have permission to start a new academic school year. They accused Poles of being hostile toward German science and that they had acted in bad faith. All of this was a carefully scripted lie. The professors, lecturers and doctors were rounded up, arrested and deported to prison facilities. They eventually were sent to Sachsenhausen concentration camp.
The first to be imprisoned to Sachsenhausen were political opponents and criminals, real or imagined. In later years, however, Jews, homosexuals, Jehovah’s Witnesses, Roma and Sinti (Gypsies) were also imprisoned in Sachsenhausen.
November 6, is a date set aside to honor those Polish academics who were victimized by Nazi rule. The Rector of the university lays wreaths to honor those fallen. See the article here.
