Overview
The Kingdom of Bithynia (Ancient Greek: Βιθυνία) was a Hellenistic kingdom centred in the historical region of Bithynia, which seems to have been established in the 4th century BC. In the midst of the Wars of the Diadochi, Zipoites assumed the title of king (basileus) in 297 BC. His son and successor, Nicomedes I, founded Nicomedia, which soon rose to great prosperity. During his long reign (c. 278 – c. 255 BC), as well as those of his successors, Prusias I (r. c. 228 – 182 BC), Prusias II (r. c. 182 – 149 BC) and Nicomedes II (r. c. 149 – 127 BC), the Kingdom of Bithynia prospered and had a considerable standing and influence among the minor monarchies.
