Wilhelmstraßen-Prozess
In March 1948, Horthy returned to testify at the Ministries Trial, the last of the twelve U.S.-run Nuremberg Trials; he testified against Edmund Veesenmayer, the Nazi administrator who had controlled Hungary during the deportations to Auschwitz in the spring of 1944. Veesenmayer was sentenced to 20 years imprisonment but was released in 1951.
