Six million Jews were murdered during the Holocaust, alongside the millions of other people killed under Nazi persecution of other groups and in genocides that followed in Cambodia, Rwanda, Bosnia and Darfur.
27 January marks the anniversary of the liberation of Auschwitz-Birkenau, the largest Nazi death camp.
The Holocaust threatened the fabric of civilisation, and genocide must still be resisted every day. Our world often feels fragile and vulnerable and we cannot be complacent. Even in the UK, prejudice and the language of hatred must be challenged by us all.
HMD is for everyone. Each year across the UK, thousands of people come together to learn more about the past and take action to create a safer future. We know they learn more, empathise more and do more.
Together we bear witness for those who endured genocide, and honour the survivors and all those whose lives were changed beyond recognition.
