Hattians
"Land of the Hatti" is the oldest known name for central Anatolia, albeit as an exonym in extraneous sources, such as the Assyrian hatti matu, found on Mesopotamian cuneiform tablets from the period of Sargon the Great of Akkad c. 2350–2150 BC; on those tablets Assyrian-Akkadian traders implored King Sargon for help.
