What important events took place in the 1920's-1940' s?

Answer 1

The 1920s, often called the "Roaring Twenties," saw significant social change, including the rise of Jazz Music, women's suffrage in the U.S., and economic prosperity followed by the Great Depression in the 1930s. The 1940s were marked by World War II, which lasted from 1939 to 1945, leading to significant global conflict, the Holocaust, and the use of atomic bombs on Hiroshima and Nagasaki. The aftermath of the war also initiated the beginning of the Cold War and the establishment of the United Nations in 1945. These decades were pivotal in shaping modern society, politics, and international relations.
