===Late Bronze===
From a bronze tablet discovered in 1986 in [[Hattusas]], a treaty between the [[Hittites|Hittite]] Great King [[Tudhaliya IV]] and his vassal, the king of [[Tarhuntassa]], defined the latter's western border at the city "Parha" and the "Kastaraya River".<ref>{{cite book|author=G.

West of Parha were the "Lukka Lands".<ref>{{cite journal | journal=British Museum Studies in Ancient Egypt and Sudan |volume=14 | title=The Arzawa letters in recent perspective |author=J.
