King Kamehameha Day celebrates the monarch that united the islands of Hawaii in 1810. The day was first celebrated in 1872 and is now an official state holiday in Hawaii.
Though the holiday is formally on June 11 each year, the islands have activities honoring the King throughout the week and weekend. Islanders celebrate with parades and ceremonies, and his statues are draped with leis.
