Bithyni

The Bithyni (Βιθυνοι; Bithyni) were a Thracian tribe who lived in Bithynia.

History
The Bithyni originally lived in the area of the lower Strymon river, due to which the ancient Greeks claimed that they were originally called the Strymoni (Στρυμονιοι; Strymonii).

Around c. 700 BC, the Paeonians displaced the Bithynians in the Strymon valley, after which they Bithyni migrated eastwards, and crossed the Thracian Bosporus and settled in northwestern Anatolia, where they assimilated the Phrygians and the Bebryces, with the region becoming known as Bithynia after them. The Dolonci tribe, who lived in the Thracian Chersonese and whom Greek mythology claimed were related to the Bithyni, might have been remnants of the Bithyni who were left behind on the European side of the Thracian Bosporus.

By the mid-6th century BC, the Bithyni had come under the rule of the Lydian empire, after which it became part of the Persian Achaemenid Empire when Cyrus II annexed Lydia.

Culture
The Bithyni used the round peltē shield in warfare.
