Lunalilo (William Charles Lunalilo; January 31, 1835 – February 3, 1874) was the sixth monarch of the Kingdom of Hawaii from his election on January 8, 1873, until his death a year later.
Born to Kekāuluohi and High Chief Charles Kanaʻina, he was of royal descent and a grandnephew of King Kamehameha I. He was educated at the Royal School by American missionaries and was proclaimed eligible for the throne by King Kamehameha III. After the death of King Kamehameha V, he was elected to the throne in 1873 by a unanimous decision of the legislature of the kingdom. Due to his popularity and status as Hawaii's first elected monarch, he became known as "The People's King". He died a year later from tuberculosis.
William Charles Lunalilo was born on January 31, 1835, in a two-story house made of coral brick, an area known as Pohukaina, now part the grounds of the ʻIolani Palace in Honolulu. His mother was High Chiefess Miriam Auhea Kekāuluohi (later styled as Kaʻahumanu III) and his father was High Chief Charles Kanaʻina. He was grandnephew of Kamehameha I by blood and the monarch's stepson by marriage to his mother. His grandmother was Kalākua Kaheiheimālie, sister of Kamehameha's favorite wife, Queen Kaʻahumanu. This made him both, a second cousin as well as first cousin to King Kamehameha V, King Kamehameha IV, and Princess Victoria Kamāmalu through their mothers: Kekāuluohi and Kīnaʻu (later styled as Kaʻahumanu II) who were half-sisters. Lunalilo translates as Luna (high) lilo (lost) or "so high up as to be lost to sight" in the Hawaiian language. He was also named after King William IV of the United Kingdom, a great friend of the Hawaiian royal family.
In the 2000 publication; "Kamehameha's Children Today", authors Charles Ahlo, Rubellite Kawena Kinney Johnson and Jerry Walker state that Lunalilo's father, Charles Kanaʻina was the great-great grandson of Kamehameha I. Kanaʻina's maternal grandfather, Palila Nohomualani was Kamehameha I's grandson through the monarch's first born child named Kahiliʻōpua, daughter of Kalola-a-Kumukoa, also known as Kalolawahilani.
