It was Pausanias who was the architect of the combined Greek victory at the Battle of Plataea (479 BC).[7] After Pausanias fell into disfavor and was accused of plotting treason, Leonidas's son Pleistarchus ruled with the other king of Sparta, Leotychidas II (and then his grandson Archidamus) until his death 459/458 BC.[2]
