It is an indisputable fact that World War II brought remarkable changes in the 20th century. Major leaps were taken in technological sectors of warfare. World War II is the most outrageous and atrocious war ever happened in the history. The exact number of casualties in the war is unknown; however, records state that around 50 million civilians and military officials were killed. The primary opponents were designated as the Axis nations(Germany, Italy, Japan and other smaller nations) and the Allied nations(Britain, Union of Soviet Socialist Republics and the United States of America). The Allies emerged as victors and significant post-war changes were observed including Women's Rights movement, termination of European Colonialism, and Civil Rights movement in the US. It's a known fact that the two superpowers – USA and USSR- rose after the conclusion of World War II to begin a cold war with each other which is still prevalent in today's date.
