Šuppiluliuma I

Another weak phase followed Tudhaliya I, and the Hittites' enemies from all directions were able to advance even to Hattusa and raze it. However, the Kingdom recovered its former glory under Šuppiluliuma I (c. 1350 BC), who again conquered Aleppo, Mitanni was reduced to vassalage by the Assyrians under his son-in-law, and he defeated Carchemish, another Amorite city-state.
