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 observed in 1921, during the First Red Scare. It was originally called “Americanization Day,”and it was intended to replace the May 1 (“May Day”) celebration of the International Workers’ Day which commemorates the 1886 Haymarket affair in Chicago.
During the Second Red Scare, it was recognized by the U.S. Congress on April 27, 1955, and made an official reoccurring holiday on July 18, 1958 (Public Law 85-529).President Dwight D. Eisenhower proclaimed May 1, 1955, the first observance of Loyalty Day. In 1958, Eisenhower urged Congress to move Child Health Day to the First Monday in October, to avoid conflicting with Loyalty Day. Loyalty Day has been recognized with an official proclamation every year by every president since its inception as a legal holiday in 1958.
