The 20th century was very eventful.In the first half of the century，the United States fought two devastating world wars and experienced the worst economic depression in its history.By the end of World WarⅡ，the United States was very different from what it had been at the end of the 19th century.The two world wars greatly increased the country’s industrial production capacity and helped to make it the most powerful country in the world.The U.S.government expanded its power and became more involved in people’s lives.Postwar developments in the 60s and 70s greatly changed American society and the United States became the sole superpower by the end of the 20th century as the Soviet Union collapsed in 1990.
