This camp was located near the village of Sachsenhausen, in north Germany. It was built in 1936 as a part of 3 camps including Buchenwald and Dachau. The early prisoners of the camp were 10,000 Jewish people from Berlin and Hamburg. 200,000 people were in the camp and 100,000 of them ended up dying from disease, exhaustion, and over working in the local factories. A lot of the rest were brought to many other death camps. The SS established the Sachsenhausen concentration camp as the principal concentration camp for the Berlin area. Located near Oranienburg, north of Berlin, the Sachsenhausen camp opened on July 12, 1936, when the SS transferred 50 prisoners from the Esterwegen concentration camp to begin construction of the camp. The number of Jewish prisoners in Sachsenhausen varied over the course of the camp's existence, but ranged from 21 at the beginning of 1937 to 11,100 at the beginning of 1945. During the nationwide Kristallnacht ("Night of Broken Glass") pogrom of November 1938, Reichsführer SS (SS chief) and Chief of German Police Heinrich Himmler ordered the arrest of up to 30,000 Jews. The SS transported those arrested to Sachsenhausen, Dachau, and Buchenwald concentration camps. Almost 6,000 Jews arrived in Sachsenhausen in the days following the Kristallnacht riots.
