Choma (Greek: Χῶμα, romanized: Chōma) was a Byzantine fortress in central Anatolia, which played an important role in the fight against the Seljuk Turks in the late 11th and 12th centuries.
[2] Its troops, the so-called Chomatenoi (Χωματηνοί), figure frequently in the campaigns of Nikephoros III Botaneiates (r. 1078–1081) and Alexios I Komnenos (r. 1081–1118).
[2] Due to its strategic location on one of the roads leading to the interior of Anatolia, it became a major base of operations for the Komnenian emperors' campaigns to push back the Turks.
Choma finally fell to the Turks a short time after the dissolution of the Byzantine Empire by the Fourth Crusade in 1204.
[2] The nearby fortress of Soublaion, which was rebuilt by Emperor Manuel I Komnenos (r. 1143–1180) in 1175 but abandoned after the Battle of Myriokephalon the next year, was formerly identified by William Mitchell Ramsay with Choma.
