World War 2 was fought between the Allied Powers and the Axis Powers from 1939 to 1945. Some key events included the flag raising on Iwo Jima in 1945 showing American victory in the Pacific, a nurse celebrating the war's end with a kiss in Times Square, and the end of the war bringing relief but also continued oppression as millions endured the Holocaust. Sources included websites documenting photos and pivotal battles on the European and African fronts.
