Kussara (Kushshar) was a kingdom of the Bronze Age in Anatolia. The kingdom, though apparently important at one time, is mostly remembered as the origin of the dynasty that would form the Old Hittite Kingdom. The Kussaran king Pithana, with his son Anitta, forerunners of the later Hittite kings, conquered Kanesh (Nesa) and its important trade centrum in roughly 1780 BC. The seat of the Kussaran dynasty was then moved to Kanesh, though Kussara appears to have retained ceremonial importance. Anitta took the title of 'Great King' when he defeated the polities of Zalpuwa and Hattum. Pithana and Anitta are the only two recorded kings of Kussara, and their exploits are known chiefly from the so-called 'Anitta Text,' one of the earliest inscriptions in the Hittite language yet discovered. A further king, Labarna I is accepted as a king of Kussara by most scholars.Hattusili I, recognized as one of the first Hittite kings, referred to himself as 'man of Kussara,' but moved his capital from there to Hattusa (from which he likely took his name). It is clear, however, that even after the capital was moved, Kussara retained some importance, as it was there that Hattusili would call a council on his own succession.
Kussara is occasionally mentioned in the clay tablets of the old Assyrian trade period of Anatolia (as Ku-ša-ra) and less often in the early Hittite Kingdom (as KUR URU Ku-uš-ša-ra). The borders of Kussara are unknown and the old city of Kussara has not been found, though several proposals for its placement have been advanced. For instance, Massimo Forlanini, an expert in the geography of ancient Anatolia, has stated that Kussara was probably situated southeast of Kanesh, but presumably north of Luhuzzadia/Lahu(wa)zzandiya, between Hurama and Tegarama (modern day Gürün), perhaps on a road which was crossing another road to the north in the direction of Samuha. Professor Trevor Bryce, meanwhile, says "[t]he city of Kussara probably lay to the south-east of the Kizil Irmak basin in the anti-Taurus region, on or near one of the main trade routes from Assyria and perhaps in the vicinity of modern Şar (Comana Cappadocia)."
