Auschwitz was the largest Nazi death camp measuring 5,000 football fields and also the deadliest, claiming an estimated 1.1 million lives.

Sunday, Jan. 27 marked the 74th anniversary of the Auschwitz liberation by the Soviet forces. It has been designated as International Holocaust Remembrance Day.

The Holocaust survivors gathered together at Auschwitz in Poland on Sunday and had a ceremony there. People there felt that people today have to understand what happened back then, and how to prevent something like that from ever happening again.

In an interview with NPR, President Trump said, “To remember these men and women – those who perished and those who survived – is to strive to prevent such suffering from happening again.”

Sunday was to remember all those who had lost their lives at Auschwitz and to help people understand what happened and how to prevent it.

There is the Auschwitz Museum also located in Poland for people to understand more about the Holocaust and what happened during World War II.
