The 1881 world tour of King Kalākaua of the Hawaiian Kingdom was his attempt to save the Hawaiian culture and population from extinction by importing a labor force from Asia-Pacific nations. His efforts brought the small island nation to the attention of world leaders, but sparked rumors that the kingdom was for sale. Critics in Hawaii believed the labor negotiations were just an excuse to see the world. The 281-day trip gave Kalākaua the distinction of being the first monarch to circumnavigate the globe; his 1874 travels had made him the first reigning monarch to visit the United States and the first honoree of a state dinner at the White House.
