By the 1920s, a majority of the US population lived in cities rather than in rural areas. In this video, Kim explores the economic opportunities cities offered to women, migrants, and immigrants, as well as the passage of new immigration restrictions.
In this second video giving an overview of World War II, we see Germany and the Axis powers only continue to gain momentum in 1940.
In 1941, the Axis gains further momentum with control of most of Continential Europe. Hitler decides to break pact and invade Stalin's Soviet Union. United States enters World War II after Japanese attack on Pearl Harbor.
In 1942 we see the Axis get pushed back in North Africa and get bogged down in the Soviet Union. The tide of war turns in favor of the Allies.
In 1943, the tide really turns in favor of the Allies in World War II. They are able to push the Axis out of N.Africa and force a surrender from Italy (along with Mussolini being deposed). The Soviets are able to start pushing the Axis out of the Soviet Union.
As we go into 1944, we see the allies land at Normandy, liberate France and face Germany in their last major counteroffensive at the Battle of the Bulge. On the Eastern Front, the Soviets end Siege of Leningrad and begin to push through Poland and Romania. In the south, Allies land in southern France and take Rome.
1945 marks the end of World War II. V-E Day (Victory in Europe Day) is May 8th 1945. War doesn't end in the Pacific until August of 1945 with the atomic bombing of Hiroshima and Nagasaki.
In 1944, the Americans (and Allies) make even more progress in the Pacific. By the end of the year, they have taken positions that put them within bombing range of Japan.
