On April 11, a memorable date is celebrated all over the world — the International Day of Liberation of Prisoners of Nazi Concentration Camps. It was erected in memory of the international uprising of prisoners of the Buchenwald concentration camp, one of the largest and most brutal death factories, which took place on April 11, 1945.

 

Concentration camps are places of detention for large numbers of people who are placed there on political, social, racial, religious and other grounds. They became widespread during the Second World War and were located both in nazi Germany itself and in the territories occupied by it.
