King Anaxandridas (in the 500s) had two wives who produced sons; his second wife gave birth first (to Cleomenes). Then his first wife gave birth to three sons, the oldest of whom was Dorieus. The question was whether the son of the second wife, Cleomenes, should inherit the throne, or whether the first born of the first wife, Dorieus, should inherit the throne? Cleomenes, being the oldest, inherited the kingship. There was clearly a debate as Dorieus left Sparta.
