Kaikilani
Kaikilani was a legendary figure in Hawaiian native oral tradition who dates to around the 16th century in the western calendar. She was married to Lonoikamakahiki (Lono) who was heir to the throne of the main island, the moiship. When the king died Lono did not feel he was ready for the responsibility of kingship and declined to rule until he had mastered the martial skills. Kaikilani stepped into his place and ruled as the first chieftess in Hawaiian history. When Lono had shown his martial skills to the satisfaction of his subjects he returned and took up the throne.
A crater on the planet Venus has been named Kaikilani in her honour, see List of craters on Venus.
