Fanorona originated in Madagascar. According to a popular legend, an astrologer advised King Ralambo to choose his successor by selecting a time when his sons were away from the capital to feign sickness and urge their return; his kingdom would be given to the first son who returned home to him. When the king’s messenger reached Ralambo’s elder son, he was playing fanorona. His younger brother arrived earlier and inherited the throne.
