Hilakku

Hilakku was one of the Neo-Hittite states during the Iron Age in southern Anatolia during the 1st millennium BC.
Hilakku was north of the Neo-Hittite state of Tabal, west of Que, and north of the Mediterranean sea. It covered the land of Cilicia Tracheia, (Latin Aspera) of the Classical age, otherwise known as 'Rough Cilicia'. It was also within the south-eastern frontiers of the Hittite appanage domain of Tarhuntassa.
