Geography

The Hittite kingdom was centered on the lands surrounding Hattusa and Neša (Kültepe), known as "the land Hatti" (Ha-at-ti). After Hattusa was made the capital, the area encompassed by the bend of the Kızılırmak River (Hittite Marassantiya, Greek Halys) was considered the core of the Empire, and some Hittite laws make a distinction between "this side of the river" and "that side of the river". For example, the bounty for an escaped slave who had fled beyond the river is higher than for a slave caught on the near side.

To the west and south of the core territory lay the region known as Luwiya in the earliest Hittite texts. This terminology was replaced by the names Arzawa and Kizzuwatna with the rise of those kingdoms. Nevertheless, the Hittites continued to refer to the language that originated in these areas as Luwian. Prior to the rise of Kizzuwatna, the heart of that territory in Cilicia was first referred to by the Hittites as Adaniya. Upon its revolt from the Hittites during the reign of Ammuna, it assumed the name of Kizzuwatna and successfully expanded northward to encompass the lower Anti-Taurus Mountains as well. To the north lived the mountain people called the Kaskians. To the southeast of the Hittites lay the Hurrian empire of Mitanni.

At its peak during the reign of Muršili II, the Hittite empire stretched from Arzawa in the west to Mitanni in the east, and included many of the Kaskian territories north as far as Hayasa-Azzi in the far north-east, as well as south into Canaan near the southern border of Lebanon.
