On April 2, 1917, President Woodrow Wilson went before a joint session of Congress to request a declaration of war against Germany. Wilson cited Germany’s violation of its pledge to suspend unrestricted submarine warfare in the North Atlantic and the Mediterranean, as well as its attempts to entice Mexico into an alliance against the United States, as his reasons for declaring war. On April 4, 1917, the U.S. Senate voted in support of the measure to declare war on Germany. The House concurred two days later. The United States later declared war on German ally Austria-Hungary on December 7, 1917.
The Manhatten project was the effort by the United States government to develop the first atomic bomb during the second world war, starting in 1942. The project involved the efforts of many famous physicists, notably Oppenheimer, Einstein, and Feynman and took place at the government research centre in Los Alamos, New Mexico.
The project was ultimately successful in 1945, and resulted in the creation of the first two deployed nuclear weapons: Fat Man and Little Boy.
Assistance on the project was provided by the governments of Canada and the United Kingdom.
