In the days before Germany surrendered on May 8, 1945, President Harry S Truman appointed Associate Supreme Court Justice Robert H Jackson to be the chief prosecutor representing the United States in the proposed trials for the European Axis powers. Jackson helped lead the Allies—American, British, French, and Soviet governments—to an agreement called the London Charter, setting the procedures for the Nuremberg Trials. The London Agreement created the International Military Tribunal (IMT) on August 8, 1945, where each of the four Allied nations appointed a judge and a prosecution team.
