Karaindaš was one of the more prominent rulers of the Kassite dynasty and reigned towards the end of the 15th century BC. An inscription on a tablet detailing building work calls him “Mighty King, King of Babylonia, King of Sumer and Akkad, King of the Kassites, King of Karduniaš,” inscribed ka-ru-du-ni-ia-aš, probably the Kassite language designation for their kingdom and the earliest extant attestation of this name.

Kassite deities were the pantheon of the Kassites, a group inhabiting parts of modern Iraq, as well as Iran and Syria, in the second and first millennia BCE. A dynasty of Kassite origin ruled Babylonia starting with the fifteenth century BCE. Kassites spoke the Kassite language, known from references in Mesopotamian sources. Many of the known Kassite words are names of Kassite deities. Around twenty have been identified so far. The evidence of their cult is limited, and only two of them, Šuqamuna and Šumaliya, are known to have had a temple. Other well attested Kassite deities include the presumed head god Ḫarbe, the weather god Buriaš, the sun god Saḫ and the deified mountain Kamulla.
