|Background story:||Since the Treaty of Nymphaeum in 1214, the Latin Empire of Constantinople had controlled the northwestern littoral of Asia Minor, from Nicomedia to Adramyttium, as well as the Mysian plain.
In 1222, the energetic founder of the Nicaean Empire, Theodore I Laskaris, died, and was succeeded by his son-in-law, John III Doukas Vatatzes. The succession was disputed by Theodore's brothers, the sebastokratores Isaac and Alexios, who rose up in revolt and requested the aid of the Latin emperor, Robert of Courtenay.
At the head of a Latin army, they marched against Vatatzes.
The two armies met at Poimanenon, south of Cyzicus, near a church dedicated to the Archangel Michael. In the ensuing battle, Vatatzes achieved a decisive victory; among the captives taken were the two Laskaris brothers, who were blinded.

|Aftermath:||The victory opened the way for the recovery by the Byzantines of most of the Latin possessions in Asia. Threatened both by Nicaea in Asia and Epirus in Europe, the Latins sued for peace, which was concluded in 1225. Most of Asia Minor was lost for them.|
