When he returned from Athens after having fought an unsuccessful battle, his enemies brought him to trial. The court for a king of the Lacedaemonians was held by the men called Elders, twenty-eight in total, along with the magistrates of the ephors, and together with them sat also the king from the other royal house. Fourteen of the Elders, joined by Agis, the king from the other royal house, found Pausanias guilty of wrongdoing.
