Kaʻiulani (pictured) was appointed the heir apparent to the throne of the Hawaiian Kingdom.

Princess Kaʻiulani was a Hawaiian royal, the only child of Princess Miriam Likelike, and the last heir apparent to the throne of the Hawaiian Kingdom. She was the niece of King Kalākaua and Queen Liliʻuokalani. After the death of her mother, Kaʻiulani was sent to Europe at age 13 to complete her education under the guardianship of British businessman and Hawaiian sugar investor Theo H. Davies. She had not yet reached her eighteenth birthday when the 1893 overthrow of the Hawaiian Kingdom altered her life. The Committee of Safety rejected proposals from both her father Archibald Scott Cleghorn, and provisional president Sanford B. Dole, to seat Kaʻiulani on the throne, conditional upon the abdication of Liliʻuokalani. The Queen thought the Kingdom's best chance at justice was to relinquish her power temporarily to the United States.

An heir apparent is a person who is first in the order of succession and cannot be displaced from inheriting by the birth of another person. A person who is first in the current order of succession but could be displaced by the birth of a more eligible heir is known as an heir presumptive.

The Hawaiian Kingdom, also known as the Kingdom of Hawaiʻi, was an archipelagic country from 1795 to 1893, which eventually encompassed all of the inhabited Hawaiian Islands. It was established in 1795 when Kamehameha I, then Aliʻi nui of Hawaii, conquered the islands of Oʻahu, Maui, Molokaʻi, and Lānaʻi, and unified them under one government. In 1810, the Hawaiian Islands were fully unified when the islands of Kauaʻi and Niʻihau voluntarily joined the Hawaiian Kingdom. Two major dynastic families ruled the kingdom, the House of Kamehameha and the House of Kalākaua.
