Problem:Question: How old was Kahekili II's son when his father conquered O'ahu? Passage:The island has been inhabited since at least 3rd century A.D. The 304-year-old Kingdom of Oahu was once ruled by the most ancient alii in all of the Hawaiian Islands. The first great king of Oahu was Mailikukahi, the lawmaker, who was followed by many generation of monarchs. Kualii was the first of the warlike kings and so were his sons. In 1773, the throne fell upon Kahahana, the son of Elani of Ewa. In 1783, Kahekili II, King of Maui, conquered Oahu and deposed the reigning family and then made his son, Kalanikupule, king of Oahu. Kamehameha the Great would conquer in the mountain Kalanikupule's force in the Battle of Nuuanu. Kamehameha founded the Kingdom of Hawaii with the conquest of Oahu in 1795. Hawaii would not be unified until the islands of Kauai and Niihau surrendered under King Kaumualii in 1810. Kamehameha III moved his capital from Lahaina, Maui to Honolulu, Oahu in 1845. Iolani Palace, built later by other members of the royal family, is still standing, and is the only royal palace on American soil.
