Agathocles (Ancient Greek: Ἀγαθοκλῆς, Agathoklḗs; 361–289 BC) was a tyrant of Syracuse from 317 BC and king of much of Sicily from 304 BC until his death. Agathocles began his career as a military officer, and raised his profile as a supporter of the democratic faction in Syracuse against the oligarchic civic government. His opponents forced him into exile and he became a mercenary leader. He eventually made his way back to Syracuse and was elected as a general. A few years later he took control through a coup d'état. In practice he was a tyrant, although a democratic constitution theoretically remained in force.
Agathocles had led a long, costly war against the Carthaginians, who ruled the western half of Sicily, between 311 and 306 BC. In a military campaign he led the invasion of Carthage's North African heartland in 310 BC. After initial successes he abandoned his army in Africa and returned to Sicily in 307 BC, where he made peace with the Carthaginians and restored the status quo ante bellum. He then assumed the royal title and managed to bring almost the entire Greek portion of Sicily, and part of Calabria, under his control. Agathocles came close to of bringing the entirety of Magna Graecia under his control but his attempt to establish a dynasty fell apart as a result of conflict within his family.
