Odilo Lothar Ludwig Globocnik was a Nazi Party official from Austria and a perpetrator of the Holocaust. A high-ranking leader of the SS, Globocnik played a leading role in Operation Reinhard, the organized murder of around one and a half million Jews, mostly of Polish origin, during the Holocaust in the Majdanek, Treblinka, Sobibór and Bełżec extermination camps. Historian Michael Allen described him as "the vilest individual in the vilest organization ever known". Globocnik killed himself shortly after his capture and detention by British soldiers.

Operation Reinhard or Operation Reinhardt was the codename of the secret German plan in World War II to exterminate Polish Jews in the General Government district of German-occupied Poland. This deadliest phase of the Holocaust was marked by the introduction of extermination camps. The operation proceeded from March 1942 to November 1943; about 1.47 million or more Jews were murdered in just 100 days from late July to early November 1942, a rate which is approximately 83% higher than the commonly suggested figure for the kill rate in the Rwandan genocide. In the time frame of July to October 1942, the overall death toll, including all killings of Jews and not just Operation Reinhard, amounted to two million killed in those four months alone. It was the single fastest rate of genocidal killing in history.
