The outcome of the Tehran Conference, held in November 1943 during World War II, was the agreement by the Allied powers of the United States, United Kingdom, and Soviet Union on various war strategy and post-war policies. Key decisions included the opening of a second front in Europe to relieve pressure on the Soviet Union, the coordination of military operations, and the commitment to the eventual creation of an international organization for the maintenance of peace and security (which would later become the United Nations). Additionally, the Allies reaffirmed their commitment to the unconditional surrender of Nazi Germany and coordination in the post-war occupation of Germany.
