The 1920s Americans experimented with many new customs and social traditions during the 1920s. There were new dances, new kinds of clothes and some of the most imaginative art and writing ever produced in the United States. Many people labeled the period “The Roaring Twenties”, to show the exuberance and vitality of the artistic and social scenes. But in most ways, the 1920s were a conservative time in American life. Voters elected three conservative Republican presidents: Warren Harding, Calvin Coolidge and Herbert Hoover. And they supported many conservative social and political policies. Most Americans in the 1920s shared some ties through blood or marriage to the first Americans who came from Britain. Many people with these kinds of historic ties considered themselves to be real Americans, true Americans. Americans traditionally welcomed newcomers from such western European countries as Britain, France, or Germany. But most of the people coming to New York City and other harbors in the 1920s arrived from the central, eastern and southern areas of Europe. Some Americans soon worried about these millions of people arriving at their shores. They worried that the immigrant newcomers might steal their jobs. Or they feared the political beliefs of the immigrants. Pressure to control immigration increased following World War I. Congress passed a bill that set a limit on how many people would be allowed to enter from each foreign country. The nineteen twenties were a time of economic progress for most Americans. During the administrations of President Warren Harding and President Calvin Coolidge, many companies grew larger, creating new jobs. Wages for most Americans increased. Many people began to have enough money to buy new kinds of products. The strong economy also created the right environment for many important changes in the day-to-day social life of Americans. The nineteen twenties are remembered now as an exciting time that historians call the “Roaring Twenties.”
