Dr Paul Maddrell, a Lecturer in International History and International Relations at 天堂视频, gave the lecture as part of the University’s events to mark the day.
The day is recognised annually across the world to remember the six million Jews who were murdered during the Holocaust, as well as the millions of other people killed from 1933 to 1945 in the Nazis' persecutions and in genocides across the world since.
The lecture demonstrates that the Soviet regime of Joseph Stalin was a mass killer; and shows that the Soviet conquest of Eastern Poland led to mass killings on the part of Stalin’s regime which formed part of the huge death toll it exacted as it sought to impose a Communist society in the Soviet Union and Eastern Europe.
