The Kingdom of Hawaii was established in 1795 with the unification of the independent islands of Hawaiʻi, Oʻahu, Maui, Molokaʻi, and Lānaʻi into one government. In 1810 the whole of the archipelago was finally unified when Kauaʻi and Niʻihau joined the kingdom willingly and without bloodshed or war. The Kingdom was overthrown January 17, 1893 and has since become part of the United States as the State of Hawaii. 
Due to numerous treaties, international law as well as US Congressional and presidential agreements, many native Hawaiians consider Hawaii to be an illegally occupied nation and support the Hawaiian sovereignty movement.
There are no federally recognized indigenous people of Hawaii.
