Former
Byzantine domains in
Anatolia had come under the rule of the
Seljuk Sultanate of Rum and other Islamic states sometime after the
Battle of Manzikert in 1071. The Sultan of Rum,
Kaykhusraw II () suffered a major defeat by the
Mongol Empire at the
Battle of Köse Dağ in 1243. The invading Mongol army further pushed Turkoman tribes to the peripheries of the peninsula, including the Byzantine frontier. The father of Karasi (or Carases as attested by
Nicephorus Gregoras) was Kalam (identified as Calames by Gregoras). The epitaphs of members of a Karasi family in
Tokat in central
Anatolia (modern-day
Turkey) dated 1415, Kutlu Melek and his son Mustafa Chelebi, trace their ancestry to the
Danishmendids, a dynasty that ruled northeastern Anatolia during the 11–12th centuries. Some historians such as
İsmail Hakkı Uzunçarşılı note the connection between the Danishmendids and the Karasids in their works. In contrast, orientalist and historian
Claude Cahen argues that the homonymy between the central Anatolian family and the Karasid dynasty in northwestern Anatolia may not be sufficient evidence for a connection. Historian
Clifford Edmund Bosworth describes the theory connecting the dynasty to the Danishmendids as "almost certainly legendary". While historian
Elizabeth Zachariadou agrees that "
Malik Danishmend", the first Danishmendid ruler, is a remote ancestor of the Karasids, she highlightes that other names mentioned in the epitaphs are echoed in earlier medieval sources. Based on the epitaphs, "Baghdi Bey" or "Yaghdi Bey" was the father of Kalam Shah, who was the father of Karasi Khan. Zachariadou favores the reading of "Baghdi" as it alignes with , a ruler mentioned by the Byzantine writer
George Pachymeres. The names of Karasi and Kalam might have been connected to two towns near
Germa, Akarasos and Kalamos. Zachariadou observes that Karasi is not a Turkish name and may have been taken from the name of the town he controlled, as was the case with other Turkish emirs, such as "
Izmir oghlu". Karasi was connected to the name "Kara Isa" () by some authors, though this interpretation was rejected by Uzunçarşılı. The name Kalam might have been Turkish as it is attested in Byzantine sources as the name of a (godfather), who was a Christianized Turk. ==Reign==
