National Loyalty Day is celebrated annually on May 1 in the United States to express loyalty to the country. The day originated during the First Red Scare as a response to far-left extremism and was initially known as Americanization Day. It was recognized by the U.S. Congress in 1955 amid concerns about the rise of communism, and in 1958, President Dwight D. Eisenhower declared it a legal holiday. The observance of National Loyalty Day involves raising the U.S. flag on important government buildings and organizing ceremonies such as parades and events in schools. The primary aim of the day is to foster a sense of patriotism among Americans and to reflect on the nation's history and the value of freedom.
