On this day in 1945 Soviet forces liberated Auschwitz-Birkenau. It was the largest concentration and death camp. 1.1 million people, 90% of them Jews, were murdered there. Today it is an international day of commemoration, to honor the memory of all victims of Nazi extermination.

A few things to keep in mind on International Holocaust Remembrance Day:

1) The Soviet liberation of Auschwitz is a deeply symbolic event, but it is worth noting that allied forces were liberating Nazi camps until May of 1945. Unspeakable suffering and death continued for months

I bring this up because the popular perception of events is informed by primary school practices which present them with clean start and stop dates. Useful for repeating dates, but less useful for having an understanding of what forces you unleash and what it takes to unwind them

When we talk about the lessons of the Holocaust, too many fall into the trap of "if it's not identical to Auschwitz, it's not worth invoking the Holocaust."

The seeds for the Holocaust were laid long before Auschwitz was opened, and the Holocaust continued after its liberation.

2) Every year on this date you can reliably expect a debate on what it is we are commemorating. A small but loud group of people use this date as an opportunity to play suffering olympics. Resist the urge to engage with these fools.
