Like the other languages of the non-Semitic tribes of Elam that of the Kassites was agglutinative; a vocabulary of it has been handed down in a cuneiform tablet, as well as a list of Kassite names with their Semitic equivalents.
Some of the Kassite deities were introduced into the Babylonian pantheon, and the Kassite tribe of Khabira seems to have settled in the Babylonian plain.
About 1330 B.C. Khurba-tila was captured by Kuri-galzu III., the Kassite king of Babylonia, but a later prince Kidin-Khutrutas avenged his defeat, and Sutruk-Nakhkhunte (1220 B.C.) carried fire and sword through Babylonia, slew its king Zamama-sum-iddin and carried away a stela of Naram-Sin and the famous code of laws of Khammurabi from Sippara, as well as a stela of Manistusu from Akkuttum or Akkad.
1 It has also been pointed out that the employment of the sign PI for wa and the use of z for s, cited in support of the earlier date, survived in the Kassite period.
After the Kassite conquest of the country, northern Babylonia came to be known as Kar-Duniyas, " the wall of the god Duniyas," from a line of fortification similar to that built by Nebuchadrezzar between Sippara and Opis, so as to defend his kingdom from attacks from the north.
