Though Captain James Cook called the islands that he discovered in 1778 the Sandwich islands, this honor to the Earl of Sandwich would be short-lived. King Kamehameha I united the islands under his rule by 1819 as the Kingdom of Hawaii.

A couple of theories exist on the origin of the name Hawaii. One theory has it that the name comes from a combination of the words "Hawa" and "ii" and means a small or new homeland; "Hawa" meaning a traditional homeland and "ii" meaning small and raging. The other theory is that the name comes from the traditional discoverer of the islands, Hawaii Loa.
