Suppiluliuma I makes Hatti a great power

Suppiluliuma I, whose reign is dated c. 1350-1322 BCE with variations, overruns Mitanni's heartland, takes Aleppo and other Syrian kingdoms, and installs Piyassili at Carchemish. Mitanni stays a Hittite dependency until Assyria annexes it under Shalmaneser I.
