Antigonid Bithyan War (302BC)

The Antigonid-Bithyan War was a war fought between Antigonis I Monophthalmos and the Bithynian League. The distraction of this war, together with war against Rhodos, offered an opportunity for Seleukid I Nikator to launch an invasion of Syria.

By 300 BC the Bithyanians had to admit defeat and placed themselves under the suzeranity of Antigonos. This freed up forces to deal with Seleukos' invasion of Syria.
