World War I (1914–1918) and World War II (1939–1945) were cataclysmic events, which spurred Congress to address the nation’s role in the world. As foreign aggression increasingly threatened national security, Congress refined its isolationist stance by declaring war on its enemies. To prepare the country for these wars, Congress debated and passed legislation to recruit citizens to serve their country, expand the U.S. citizenry and their rights, regulate the domestic economy, and define national loyalty. These laws forever changed the nation and the everyday lives of all Americans.
