Bithynia

from 322 BCE to 74 BCE

Bithynia was an ancient region in northwestern Anatolia, near the Bosphorus and the Sea of Marmara, home to Thracian-speaking Bithynians and to Greek colonies such as Chalcedon and Heraclea. After the death of Alexander the Great it became an independent kingdom, whose first ruler took the title of king, and its capital Nicomedia, founded by Nicomedes I, grew into a major Hellenistic city. The kings balanced between the successor states and Rome. The fugitive Hannibal found refuge at the court of Prusias I. In his will Nicomedes IV left the kingdom to Rome, and it became a Roman province, later joined with Pontus. Pliny the Younger served as governor there around 110 CE, and the First Council of Nicaea took place in the Bithynian city of Nicaea in 325.
