In the postwar period, people began questioning traditional beliefs.The ideas of Albert Einstein and Sigmund Freud had an enormous impact on the 20th century. These thinkers were part of a scientific revolution as important as that brought about centuries earlier by Copernicus and Galileo.The brutality of World War I caused philosophers and writers to question accepted ideas about reason and progress. Disillusioned by the war, many people also feared the future and expressed doubts about traditional religious beliefs.World War I had disrupted traditional social patterns. New ideas and ways of life led to a new kind of individual freedom during the 1920s. Young people especially were willing to break with the past and experiment with modern values.
In both human suffering and economic terms, the cost of War I was immense. The Great War left every major European country nearly bankrupt.War’s end saw the sudden rise of new democracies. From 1914 to 1918, Europe’s last absolute rulers had been overthrown.Germany’s new democratic government was set up in 1919. Known as the Weimar Republic, it was named after the city where the national assembly met. The Weimar Republic had serious weaknesses from the start.In the late 1920s, American economic prosperity largely sustained the world economy. If the U.S. economy weakened, the whole world’s economic system might collapse. In 1929, it did.People could not pay the money they owed on margin purchases. Stocks they had bought at high prices were now worthless. Within months of the crash, unemployment rates began to rise as industrial production, prices, and wages declined.The Depression confronted democracies with a serious challenge to their economic and political systems. Each country met the crisis in its own way.
In some ways, fascism was similar to communism. Both systems were ruled by dictators who allowed only their own political party.Mussolini Takes Control Fascism’s rise in Italy was fueled by bitter disappointment over the failure to win large territorial gains at the 1919 Paris Peace Conference. Rising inflation and unemployment also contributed to widespread social unrest.In October 1922, about 30,000 Fascists marched on Rome. They demanded that King Victor Emmanuel III put Mussolini in charge of the government.When Mussolini became dictator of Italy in the mid-1920s, Adolf Hitler was a little-known political leader whose early life had been marked by disappointment. When World War I broke out, Hitler found a new beginning. He volunteered for the German army and was twice awarded the Iron Cross, a medal for bravery.
Setting the Stage. By the mid-1930s, Germany and Italy seemed bent on military conquest. The major democracies—Britain, France, and the United States—were distracted by economic problems at home and longed to remain at peace. With the world moving toward war, many nations pinned their hopes for peace on the League of Nations. As fascism spread in Europe, however, a powerful nation in Asia moved toward a similar system. Following a period of reform and progress in the 1920s, Japan fell under military rule.The League’s failure to stop the Japanese encouraged European Fascists to plan aggression of their own. The Italian leader Mussolini dreamed of building a colonial empire in Africa like those of Britain and France.Instead of taking a stand against Fascist aggression in the 1930s, Britain and France repeatedly made concessions, hoping to keep peace. Both nations were dealing with serious economic problems as a result of the Great Depression. In addition, the horrors of World War I had created a deep desire to avoid war
