Nikephoros III Botaneiates
Choma was located in the upper valley of the Maeander River in Phrygia. After the Battle of Manzikert, it became an isolated Byzantine outpost surrounded by Turkish-controlled territory. Its troops, the so-called "Chomatenoi" (Χωματηνοί), figure frequently in the campaigns of Nikephoros III Botaneiates () and Alexios I Komnenos (). 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. In the 12th century, it formed its own district, that of "Choma and Cappadocia", under a "toparches".
