…the representatives of Oberkommando der Wehrmacht, Germany’s supreme military command, signed the German Instrument of Surrender in the presence of Allied and Soviet commanders, officially ending the Second World War in Europe. (Pictured above, Chief of the Supreme High Command of the German Armed Forces Wilhelm Keitel signing the ratified surrender terms for the German military in Berlin.)
Although the 26 countries that officially opposed the Axis Powers of World War II are now best known collectively as the Allies or Allied Powers, their formal name midway through the war was the United Nations. This followed a declaration on January 1, 1942 that would form the basis of the modern U.N. (which was founded in its current form on June 26, 1945).
The names for the four leading combatants of the alliance — the U.S., U.K., Soviet Union, and China — includes The Big Four, The Trusteeship of the Powerful, and The Four Policemen.
The origin of the term Axis stems from a treaty signed by Nazi Germany and Fascist Italy in October 1936. Mussolini declared shortly after that all other European countries would henceforth rotate on the Rome-Berlin axis, thus creating the term “Axis”. The name stuck following the 1940 Tripartite Pact that brought Japan into the alliance.
