They are believed to descend from the ancient Akkadians, who emerged as the ruling class of Assyria, starting with Sargon of Akkad (grandfather of Naram-sin). Babylonia, formerly Sumer and Akkad, was a colony of Assyria. The title of "King of Babylon" was "King of Sumer and Akkad" as transliterated from the Akkadian Ðâr Mat Ðûmerî û Akkadî. Eventually Aramaean tribes, among them Chaldeans, emigrated en-masse into the region and their language became dominant. These different cultures ultimately merged, to form classic Assyrian culture. [16] Today, in certain areas of the Assyrian homeland, identity within a community is aligned to village of origin or Christian denomination, as with Chaldean for example.
