Editing Plato (section)

====Second and third trip to Syracuse====
After Dionysius I's death in 367 BC, Plato returned to Syracuse, likely early in 366 BC, at the request of Dion, in order to tutor [[Dionysius II of Syracuse|Dionysius II]] and guide him to become a [[philosopher king]]. Dionysius II seemed to accept Plato's teachings, but he became suspicious of Dion, his uncle. Dionysius expelled Dion, and Plato, after trying repeatedly to reconcile the two, gave up and returned to Athens.{{sfn|Nails|2002|p=248}} 

Plato returned to Syracuse a third time in 361 BC, likely staying over the winter until 360 BC.{{sfn|Nails|2002|p=248}} Dionysius kept Plato against his will, forcing Plato to appeal to his friend [[Archytas]] to intercede, at which point he returned to Athens.{{sfn|Nails|2002|p=248}} Dion would return to overthrow Dionysius and ruled Syracuse for a short time in 357 BC up until 354 BC,{{sfn|Nails|2002|p=248}} when he was usurped by [[Calippus of Syracuse|Calippus]], an Athenian who Plato insists, in the Seventh Letter, had no connection with the Academy.{{sfn|Nails|2006|p=10}}
