Antigonus I Monophthalmus (Ancient Greek: Ἀντίγονος ὁ Μονόφθαλμος, Antigonos the One-eyed, 382–301 BC), son of Philip from Elimeia, was a Macedonian nobleman, general, and satrap under Alexander the Great. During his early life he served under Philip II, and he was a major figure in the Wars of the Diadochi after Alexander's death, declaring himself king in 306 BC and establishing the Antigonid dynasty, which ruled most of Asia Minor (now the bulk of Turkey) and northern Syria, with his kingdom centered on Macedon.
By about 304 BCE, Antigonus had overplayed his hand, and provoked the remaining four dynasts to align against him. Antigonus was killed at the Battle of Ipsus in 301 BCE after being struck by a javelin.
Antigonos, nick-named One-eye, was locked into a struggle with various of Alexander's generals and heirs. In 312 BCE, Antigonos commissioned the polis of Rhodes to build ships for him in his war against Ptolemaios.
