Loyalty Day is observed on May 1 in the United States. It is a day set aside for the reaffirmation of loyalty to the United States and for the recognition of the heritage of American freedom.
The holiday was first celebrated in the 1930s as Americanization Day, and was intended to serve as a counterweight to May Day, which was perceived as a Communist holiday.
Loyalty Day is 'celebrated' with parades and ceremonies in communities across the United States, although many people in the United States remain unaware of it. Although a legal holiday, it is not a federal holiday.
It was made an official holiday by President Dwight D. Eisenhower on May 1, 1958 under pressure from United States Senator Karl Mundt and Representative James E. Van Zandt.
