The Hattians (ˈhætiənz) were an ancient Bronze Age people that inhabited the land of Hatti, in central Anatolia (modern Turkey). They spoke a distinctive Hattian language, which was neither Semitic nor Indo-European. Hattians are attested by archeological records from the Early Bronze Age and by historical references in later Hittite and other sources. Their main centre was the city of Hattush. Faced with Hittite expansion (since 2000 BC), Hattians were gradually absorbed (by 1700 BC) into the new political and social order, imposed by the Hittites, who were one of the Indo-European-speaking Anatolian peoples. The Hittites kept the country name ("land of Hatti") unchanged, which also became the main designation for the Hittite state. Complex questions related to etymology of endonymic terms for Hattians, their land, language and capital city (Hatti, Hattili, Hattush) are debated among scholars. Later conquerors (Hittites) did not change the name of the city (Hattush). They also adopted the regional name (Land of Hatti), and even expanded its use, transforming it into the most common designation for their entire country, that grew to be much larger than the land of ancient Hattians. It is therefore assumed that Hattian designations had some special significance already during the pre-Hittite period, and it is also accepted, as a convention among scholars, that Hattian labels can be used as designations for the pre-Hittite population of central Anatolia, although it is not known whether ethnically related inhabitants of neighboring regions and city-states (surrounding the city-state of Hattush) ever saw themselves as Hattians. The use of the term "Proto-Hittite" as a designation for Hattians is inaccurate. The Hittite language (self-designation: Nešili, "[in the language] of Neša") is an Indo-European language and thus linguistically distinct from the (non-Indo-European) Hattian language. The Hittites continued to use the term Land of Hatti for their own state.
