Columbus Day is a federal holiday that commemorates the landing of Christopher Columbus in the New World on October 12, 1492.
Columbus Day was unofficially celebrated across the country in the 18th century but did not become a federal holiday until 1937, according to the History Channel.
Although the holiday and Columbus have stirred up controversy, many celebrate to honor his achievements and Italian-American heritage. But many alternatives to the holiday have appeared in recent years.
