For the Indo-Greek king (circa 185 BC), see Agathocles of Bactria

Agathocles (361 BC - 289 BC), tyrant of Syracuse (317 BC - 289 BC) and king of Sicily (304 BC - 289 BC).

He was born at Thermae Himeraeae (modern name Termini Imerese) in Sicily. The son of a potter who had removed to Syracuse in about 343 BC, he learned his father's trade, but afterwards entered the army. In 333 BC he married the widow of his patron Damas, a distinguished and wealthy citizen. He was twice banished for attempting to overthrow the oligarchical party in Syracuse.

In 317 BC he returned with an army of mercenaries under a solemn oath to observe the democratic constitution which was then set up. Having banished or murdered some 10,000 citizens, and thus made himself master of Syracuse, he created a strong army and fleet and subdued the greater part of Sicily.

War with Carthage followed. In 311 BC Agathocles was besieged and defeated in Syracuse in battle of Himera . After defeat in 310 BC he took the desperate resolve of breaking through the blockade and attacking the enemy in Africa. In Africa he concluded the treaty with Ophellas , ruler of Cyrenaica. After several victories he was at last completely defeated (307 BC) and fled secretly to Sicily.

After concluding peace with Carthage in 306 BC, Agathocles styled himself king of Sicily in 304 BC, and established his rule over the Greek cities of the island more firmly than ever. Peace treaty with Carthage left him in control of Sicily east of the Halycus River . Even in his old age he displayed the same restless energy, and is said to have been contemplating a fresh attack on Carthage at the time of his death.

His last years were harassed by ill-health and the turbulence of his grandson Archagathus , at whose instigation he is said to have been poisoned; according to others, he died a natural death. He was a born leader of mercenaries, and, although he did not shrink from cruelty to gain his ends, he afterwards showed himself a mild and popular "tyrant." Agathocles restored the Syracusan democracy on his death bed and did not want his sons to succeed him as king.

Agathocles married Theoxena , stepdaughter of Ptolemy I of Egypt. His daughter Lanassa married to king Pyrrhus of Epirus.
