Source-derived summary

Nicomedes II Epiphanes (Greek: Νικομήδης ὁ Ἐπιφανής "Nicomedes God-Manifest") was the king of Bithynia from 149 to c. 127 BC. He was fourth in descent from Nicomedes I. Nicomedes II was the son and successor of Prusias II and Apame IV. His parents were related as they were maternal cousins.

Life

He was so popular with the people that his father sent him to Rome to limit his influence. However, in Rome, he also gained favor from the Roman Senate, forcing Prusias to send an emissary named Menas with secret orders to assassinate him. But the emissary revealed the plot, and persuaded the prince to rebel against his father.

Supported by Attalus II Philadelphus, king of Pergamon, he was completely successful, and ordered his father to be put to death at Nicomedia. During his long reign Nicomedes adhered steadily to the Roman alliance, and assisted them against the pretender to the throne of Pergamon Eumenes III. He was succeeded by his son Nicomedes III.

Nicomedes introduced the Bithynian era for numbering years on his coins.

Editorial reviewStrongest as a route into the people, institutions and dated events that shaped the subject’s public record. The current 175-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The linked authority record independently contributes the date -0200-01-01. Its strongest next move is a source search built around Nicomedes, Bithynia and king.
Editorial analysis

Why this record matters

“Nicomedes II of Bithynia” is worth following because a concise public description often conceals a longer documentary argument. Here, Nicomedes, Bithynia and king provides the most credible route into that argument.

Evidence profile

Chronology provides the most reliable spine for this subject; interpretation should follow only after identities and dates are secure. The source revision retrieved here is dated Jun 11, 2026. The linked authority identifier is Q465838. 1 of 1 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank.

Critical limits

Public reputation and documentary evidence do not always develop together; absence from a summary is not evidence of historical absence. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
