The lost generation was the generation that was reaching maturity during the 1920’s right after World War I and the men that were killed during that time. The lost generation was a sad time in history because there were a lot of teenagers who did not make it to adulthood because of World War I and the things that happened after. During the 1920’s there were a large number of deaths due to World War I. The generation was shown as the generation of getting rid of the old generation's ideas of appropriate behavior, morality, and gender roles. There were a lot of war heroes in the lost generation who were forgotten but made a huge impact. The term lost generation is used for the period from the end of World War I to to the beginning of the great depression. The lost generation and that entire era was not a good time for the U.S. Another way of talking about the lost generation is talking about the World War I generation because that is another thing that the generation was referred to as.
