Dionysius I of Syracuse

Dionysius I or Dionysius the Elder (Greek: Διονύσιος ὁ Πρεσβύτερος; c. 432 – 367 BC) was a Greek tyrant of Syracuse, in what is now Sicily, southern Italy. He conquered several cities in Sicily and southern Italy, opposed Carthage's influence in Sicily and made Syracuse the most powerful of the Western Greek colonies. He was regarded by the ancients as an example of the worst kind of despot—cruel, suspicious and vindictive.

Dionysius began his working life as a clerk in a public office. Because of his achievements in the war against Carthage that had begun in 409 BC, he was elected supreme military commander in 406 BC; in the following year he seized total power and became tyrant.

Dionysius the Elder's victory over the democratic Syracuse represents both the very worst and the very best of the mercenary-leader. Dionysius's career as a despot occurred after he was given six hundred personal mercenaries to guard his person after faking an attack on his own life. He was able to increase this guard to one thousand and gradually consolidated his power and established himself as a tyrant. He imposed his mercenaries on all parts of the polis community. Such an act would have truly wiped out any suggestion that democracy was still in force. His rule was "unconstitutional and illegitimate and could not fail to provoke rebellions among the partisans of democratic government". Dionysius' position at home would be threatened even as early as 403 by those philosophically opposed to tyranny. Interestingly, Sparta, which had in the past deposed tyrants from Corinth to Athens, did not damn Dionysius and his . In fact, relations between the two were very positive:

When the Lacedaemonians [Spartans] had settled the affairs of Greece to their own taste, they dispatched Aristus, one of their distinguished men, to Syracuse, ostensibly pretending that they would overthrow the government, but in truth with intent to increase the power of the tyranny; for they hoped that by helping to establish the rule of Dionysius they would obtain his ready service because of their benefactions to him.
