The liberation of the holocaust occured when the allied forces moved arcross Europe in 1945. When the allied forces moved in, the Germans tried to hide the many concentration camps by destroying them and sending the prisoners on "death marches". (Liberation par. 1) As the forces moved across the country, they liberated the Nazi's controlled labor camps. Different camps made different goods and services for the Nazi's. The world knew Hitler was leading a movement in Europe, but they didn't know he enslaved people and used them to work in the camps. As soon as they found out this level of inhumanity, they knew something had to be done.
