It was the greatest tragedy of the Holocaust. In just five years, over one million people were murdered at Auschwitz, the largest and deadliest Nazi concentration camp.

Auschwitz was established in 1940 and located in the suburbs of Oswiecim, a Polish city the Germans annexed. Between 1940 and 1945, it grew to include three main camp centers and a slew of subcamps – each of which were used for forced labor, torture, and mass killing.

An estimated 1.3 million people were deported to Auschwitz during its five-year operation, and approximately 1.1 million were killed.

The terror of Auschwitz finally subsided on January 27, 1945, when the Soviet Army liberated the remaining 7,000 prisoners from the camps.

On the 75th anniversary of this liberation, these photos exhibit the horror and history of Auschwitz.


Auschwitz was established in 1940 in the suburbs of Oswiecim, Poland. During its first year, authorities cleared 15 square miles for the camp.

Auschwitz I, the first camp to undergo construction, was initially created for three reasons: to imprison enemies, to use forced labor, and to kill certain groups of people.

Construction of the largest camp, Auschwitz II, also called Auschwitz-Birkenau, began in October 1941. Electrified barbed wire divided it into 10 different sections.

Auschwitz-Birkenau's different sections were for "women; men; a family camp for Roma (Gypsies) deported from Germany, Austria, and the Protectorate of Bohemia and Moravia; and a family camp for Jewish families deported from the Theresienstadt ghetto," according to the Holocaust Memorial Museum.

Inmates were put into poorly structured wooden barracks with 36 bunks each. Five to six prisoners were packed in so over 500 prisoners were in each unit.

Incoming prisoners who were selected for forced labor received tattoos and had a serial number sewn into their uniforms. Auschwitz was the only concentration camp to do this.

Shortly after construction, Auschwitz-Birkenau became the largest killing center and central location for the extermination of Jews in Europe.

In 1942, two farmhouses just outside the camp were turned into gas chambers.

But as Auschwitz-Birkenau became a central location for mass killing, these gas chambers were too small. Four new chambers were built between March and June 1943, each containing a disrobing area, gas chamber, and crematory ovens.

As millions of people were murdered, mounds of eye glasses, razors, shoes, and other belongings were left behind.

Forty-four subcamps with different specializations were established at Auschwitz between 1942 and 1944. The Nazis made prisoners work on large farms, in coal mines, in weapons production — basically anything the German military needed for war.

In January 1945, before Soviet forces could reach the camps for liberation, nearly 60,000 people were forced to march west, and thousands more were killed.

When Soviet soldiers arrived, only between 6,000 and 7,000 prisoners remained. The majority of them faced starvation, death, and illness.

Available records indicate that when the soldiers arrived, at least 700 youth prisoners were still at the camp, half of whom were Jewish.

In many cases, the liberated children were malnourished, severely weak, vitamin deficient, and diseased. Of 180 children examined after liberation, 40% had tuberculosis.

Immediately after liberation, many of the children were sent to hospitals organized by the Soviet army and the Polish Red Cross.
