The war shifted the public's focus away from domestic issues and towards the war effort. Many of the Progressive Era's most prominent leaders, such as Theodore Roosevelt and Woodrow Wilson, became involved in the war effort, and the government's attention turned to mobilizing for war. As a result, many of the reforms that had been enacted during the Progressive Era were put on hold or abandoned altogether.
Additionally, the war had a profound impact on the economy and society, leading to a period of rapid change and upheaval. After the war, the United States entered a period of economic prosperity known as the "Roaring Twenties." This period was characterized by a significant increase in consumer spending, a boom in the stock market, and an overall sense of optimism. However, the Roaring Twenties came to an abrupt end with the stock market crash of 1929 and the onset of the Great Depression, which brought about a new set of challenges and priorities for the nation.
