Holocaust Memorial Day is on the 27 January.

On this day we remember the six million Jewish people who were murdered under the regime.

We also remember the millions of other people who were killed or have been affected by Nazi persecution, as well as the people who were killed in the genocides in Cambodia, Rwanda, Bosnia and Darfur.

BBC Bitesize explores what this day means and why we mark it.

On 27 January 1945, the infamous concentration camp Auschwitz-Birkenau, in south-west Poland, was liberated by Russian troops.

27 January is now the day the world remembers the Holocaust, its victims and those from other acts of genocide throughout history.

Holocaust Memorial Day began in 2000 when 46 governments signed the Stockholm Declaration. It came about after government representatives from around the world met in Stockholm, Sweden to discuss the education, remembrance and research of the Holocaust.

The United Nations also marks 27 January as an annual International Day of Commemoration to remember the victims of the Holocaust.

This day of remembrance is a reminder of how hatred, bigotry and can cause unimaginable danger to our world. It is a call to remember, reflect and take action to ensure such horrors never happen again.

The Holocaust was a systematic, state-led persecution and murder of six million European Jews by the Nazi regime and its . It took place throughout Europe between 1933 and 1945.

It's important to recognise that when we're referring to the deaths of millions of European Jews, we are also talking about the disappearance of cultures, communities, languages and traditions.

The term Holocaust refers specifically to the genocide of Jewish people. Other groups also experienced horrific and violent persecution by the Nazis including Roma and Sinti people, Soviet civilians and prisoners of war, Polish citizens, black people, people with disabilities, political opponents of the Nazis, LGBTQ+ people, and Jehovah’s Witnesses.
