"On 28 October 1939, during a demonstration, Jan Opletal was shot. His burial on 15 November 1939 became another demonstration.[11] On 17 November 1939 (now marked as International Students' Day) the Czech University and all other Czech institutions of higher learning were closed, remaining closed until the end of the War. Nine student leaders were executed and about 1,200 Czech students were interned in Sachsenhausen and not released until 1943. About 20[12] or 35[13] interned students died in the camp. On 8 May 1940 the Czech University was officially renamed Czech Charles University (Czech: Česká universita Karlova) by government regulation 188/1940 Coll.[citation needed]
