Just as World War I stands as an important marker of the new role for the U.S. on the world stage, the war also is an important event that started a century-long growth of the federal government. Once the United States entered the war, the government grew through the administration of the draft, the organization of the war at home, and the promotion of civilian support for the war. Americans on the home front had mixed reactions to the war. Some bought Liberty bonds to support the war, while others opposed the war.
