The document discusses the major social changes in the United States during the 1920s as the country transitioned from a rural to urban society. It describes how prohibition led to clashes between traditional rural values and new secular urban cultures. Prohibition failed to stop alcohol consumption and instead empowered organized crime which fought over control of the illegal alcohol trade. By the mid-1920s, prohibition had little support and was repealed in 1933 with the 21st amendment. The 1920s was also a period of conflict between science and religion exemplified by the Scopes Monkey Trial over the teaching of evolution in schools.
