A U.S. national holiday since 1937, Columbus Day commemorates the arrival of Christopher Columbus in the New World on October 12, 1492. The Italian-born explorer had set sail two months earlier, backed by the Spanish monarchs King Ferdinand and Queen Isabella. He intended to chart a western sea route to China, India and the fabled gold and spice islands of Asia; instead, he landed in the Bahamas, becoming the first European to explore the Americas since the Vikings set up colonies in Greenland and Newfoundland during the 10th century.
In 1937, President Franklin D. Roosevelt
proclaimed Columbus Day a national holiday, largely as a result of intense lobbying by the Knights of Columbus, an influential Catholic fraternal benefits organization. Originally observed every October 12, it was fixed to the second Monday in October in 1971.
