The Belsen trials were a series of several trials that the Allied occupation forces conducted against former officials and functionaries of Nazi Germany after the end of World War II. British Army and civilian personnel ran the trials and staffed the prosecution and judges.
The Belsen trials took place in Lüneburg, Lower Saxony, Germany, in 1945 and the defendants were men and women of the Schutzstaffel as well as prisoner functionaries who had worked at various concentration camps, notably Auschwitz and Bergen-Belsen.
The first trial generated considerable interest around the world, as the public heard for the first time from some of those responsible for the mass murder in the eastern extermination camps. Some later trials are also referred to as Belsen trials.
