On 2 August, we commemorate the last 4,300 Sinti and Roma in the German Nazi concentration camp Auschwitz-Birkenau, who were murdered by the SS on that night in 1944 despite their fierce resistance. In memory of all 500,000 Sinti and Roma murdered in Nazi-occupied Europe, the European Parliament declared this date the European Holocaust Memorial Day for Sinti and Roma in 2015.
