Suppiluliuma I
After the incorporation or association of Arzawa and Mitanni (under Suppiluliuma I), the Hittite sphere of influence under Mursili II bordered on the "Hayasa-Azzi" to the east, on the "Ahhiyawa" and the newly-forming Assuwa league to the west, on Egypt-controlled Canaan to the south, and on Assyria to the south-east.
