Tukulti-Ninurta I

Tukulti-Ninurta I (1244–1207 BC), won a major victory against the Hittites and their king Tudhaliya IV at the Battle of Nihriya and took thousands of prisoners. Rather than being content to simply subjugate Babylonian kings as his predecessors had, he conquered Babylonia directly, taking Kashtiliash IV as a captive and ruled there himself as king for seven years, taking on the old title "King of Sumer and Akkad" first used by Sargon of Akkad. Tukulti-Ninurta I thus became the first Akkadian-speaking native Mesopotamian to rule the state of Babylonia, its founders having been foreign Amorites, succeeded by equally foreign Kassites. Tukulti-Ninurta petitioned the god Shamash before beginning his counteroffensive.
