On January 27, 1945, Soviet forces liberated the Auschwitz-Birkenau extermination camp, discovering the largest Nazi killing center in Europe. Auschwitz has become a symbol of the Holocaust, representing the depths of man’s inhumanity to man. Eighteen governments have legislated January 27 as an annual Holocaust Memorial Day. In November 2005, the United Nations passed a resolution to mark January 27 as an international day of commemoration to honor the victims of the Holocaust, and urged member states to develop educational programs to impart the memory of this tragedy to future generations. Holocaust Remembrance Day ceremonies will be organized on the international, national, regional and local levels, including in universities and schools.
