Antigonus I Monophthalmus was a prominent general and statesman during the era of the Macedonian Empire. He was born around 382 BC and became one of the key figures following the death of Alexander the Great in 323 BC. Antigonus played a significant role in the Wars of the Diadochi, which were fought among Alexander's former generals for control of his vast empire. Antigonus earned the nickname "Monophthalmus," meaning "one-eyed," due to losing an eye in battle. He established himself as a powerful ruler in Asia Minor and later declared himself king. His reign was marked by military campaigns and political maneuvering until his death in 301 BC at the Battle of Ipsus.
