Prusias I the Lame: king of Bithynia (r.228-182 BCE).
A son of Ziaelas, who was killed in action in 228 BCE in a battle against the Galatians, Prusias inherited a war in the east. He defeated them, but it was not his only victory: he also added Mysia to his territories, a part of Asia that had originally belonged to Byzantium. He concluded an alliance with king Demetrius II of Macedonia and married his daughter Apame III. She gave birth to a son, Prusias II the Hunter, who would succeed Prusias I.
He waged ware against king Attalus I Soter of Pergamon and captured several towns; one of these he renamed Prusias (modern Bursa). During the siege of Heraclea, a port on the southern shore of the Black Sea, he broke a leg - hence his nickname "the Lame".
Towards the end of his reign, he granted asylum to Hannibal Barca, who may have wanted him to join the Seleucid king Antiochus III the Great in the Syrian War against the Roman Republic (192-188 BCE), but Prusias remained neutral. He was succeeded by Prusias II the Hunter.
