Religion

The Cuman people practiced the shamanistic religion of Tengrism. Their belief system had animistic and shamanistic elements; they celebrated their ancestors and provided the dead with objects whose lavishness was considered an indicator to the recipient's social rank.

The Cumans referred to their shamans as Kam (female: kam katun); their activities were referred to as qamlyqet, meaning "to prophesy ". The Cumans used Iranian words to designate certain concepts: uchuchmak (a native Turkic word cognate with Turkish uçuşmak) meaning "fly away, paradise" and keshene meaning "nest" (an Iranian borrowing; the concept was that the soul has the form of a bird).

Funerals for important members involved firstly creating a mound, then placing the dead inside, along with various items deemed useful in the afterlife, a horse (like the Bulgars), and sometimes a servant or slave.

Cuman divination practices used animals, especially the wolf and dog. The dog "It/Kopec" was sacred to the Cuman–Kipchaks, to the extent that an individual, tribe, or clan would be named after the dog or type of dog. Cumans had shamans who communicated with the spirit world; they were consulted for questions of outcomes.

The Cumans in Christian territories were baptized in 1227 by Robert, Archbishop of Esztergom, in a mass baptism in Moldavia on the orders of Bortz Khan, who swore allegiance to King Andrew II of Hungary.
