Philetaerus (circa 343 BC–263 BC) was the founder of the Attalid dynasty of Pergamon in Anatolia.

He was born in Tieum¹ a small town on the Black Sea coast of Anatolia between Bithynia to the west and Paphlagonia to the east, his father was Attulus (perhaps from Macedonia) and his mother, Boa was Paphlagonian.²

After the death of Alexander the Great in 323 BC, Philetaerus became embroiled in the struggle for supremacy, called the Wars of the Diadochi (diadochi means "successors" in Greek) between Alexander's regional governors, Antigonus in Phrygia, Lysimachus in Thrace and Seleucus in Babylonia (among others). Philetaerus served first under Antigonus. He then shifted his allegiance to Lysimachus, who, after Antigonas was killed at the Battle of Ipsus in 301 BC, made Philetaerus commander of Pergamon, where Lysimachus kept a treasury of nine thousand talents.³

Philetaerus served Lysimachus until 282 BC, when perhaps because of conflicts involving the court intrigues of Arsinoë, Lysimachus' third wife, Philataerus deserted Lysimachus, offering himself and the important fortress of Pergamon, along with its treasury to Seleceus⁴ who subsequently defeated and killed Lysimachus⁵ at the Battle of Corupedium in 281 BC. Seleceus himself was killed by Ptolemy Ceraunus a brother of Arsinoë at Lysimachia a few months later.⁶

Though nominally under Seleucid control, Philetaerus, especially after the death of Seleceus, had considerable autonomy and was able with the help of his considerable wealth to increase his power and influence beyond Pergamon. There are numerous records of Philetaerus as benefactor to neighboring cities and temples, including the temples at Delphi and Delos. He also contributed troops, money and food to the city of Cyzicus for defense against the invading Gauls. As a result Philetaerus gained prestige and goodwill for himself and his family.⁷

During his nearly forty year rule, he constructed on the acropolis of Pergamon, the temple of Demeter, and the temple of Athena, (Pergamon's patron deity), and Pergamon's first palace and he added considerably to the cities fortifications.⁸

Philetaerus never married and had no children.⁹ He adopted his nephew Eumenes I (the son of Philetaerus' brother also named Eumenes), who succeeded him as ruler of Pergamon, upon his death in 263 BC.¹⁰
