From 1870 to 1950, America experienced an unprecedented era of rapid change and growth. A host of remarkable inventions led the way in transforming this nation into a major world power, and yet the forces of change often caused tremendous upheaval in people's lives. America was involved in the philosophy of isolationism toward other countries while involved in unprecedented growth. The day-to-day experiences of Americans who lived through Prohibition, the Roaring Twenties, the Great Depression, and two world wars were part of this modern age of America. Immigrants flocked to America's colorful, fast-growing cities, hoping to start anew. This was the country of dreams and growth. We lived through Henry Ford and his Model T automobile, songs of the Depression, FDR, D-Day Pearl Harbor and V-Day were all part of the modern age of America.
