question: When was the fourth Monarch in Hawaii?
answer: 1855 to November 30, 1863
context: Title: King Kalākaua's world tour
  Passage: The 1881 world tour of King Kalākaua of the Kingdom of Hawaii was his attempt to save the Hawaiian culture and population from extinction through the importation of 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.  In Hawaii there were critics who believed the labor negotiations were just his excuse to see the world.  The 281-day trip gave him the distinction of being the first monarch to circumnavigate the globe, just as his 1874 travels had made him the first reigning monarch to visit America and the first honoree of a state dinner at the White House.

  Title: List of the last monarchs in the Americas
  Passage: The Native American hereditary leaders during this time are not included.  Those that are listed as former monarchs of what is now the continental United States were heads of European seated monarchies (or Mexican monarchs, such as Agustín I of Mexico and Maximilian I of Mexico) and themselves never set foot on American soil.  Others were indigenous monarchs, such as Malietoa Tanumafili I, Tuʻi Manuʻa Elisala and Liliuokalani of Hawaii; The last monarch of each state and territory may not be the last colonial ruler (i.e. Louis XV of France is the last French monarch of Louisiana, but Napoleon Bonaparte, prior to becoming Emperor, was the last ruler of Louisiana).  Also their end of reign may not be how the US acquired these states.  One state can have more than one last monarch, since each state may have been the product of many different acquisitions by the United States.  Different claims of a foreign country are taken into account.
