International Holocaust Remembrance Day, 27 January, is an international memorial day for the victims of the Holocaust, the genocide that resulted in the annihilation of 6 million European Jews, 2 million Gypsies (Roma and Sinti), 15,000 homosexual people and millions of others by the Nazi regime. It was designated by the United Nations General Assembly Resolution 60/7 on 1 November 2005 during the 42nd plenary session. The resolution came after a special session was held earlier that year on 24 January 2005 during which the United Nations General Assembly marked the 60th anniversary of the liberation of the Nazi concentration camps and the end of the Holocaust.
27 January is the date, in 1945, when the largest Nazi death camp, Auschwitz-Birkenau, was liberated by Soviet troops.
