Shalmaneser I conquered eight kingdoms in central Anatolia

Shalmaneser I (1274–1245 BC) conquered eight kingdoms in central Anatolia in his first year, and in the next, he defeated a coalition of Hittites, Hurrians, Mitanni, and Ahlamu, annexing yet more territory in Anatolia and the Levant, and retaining Assyrian dominion over Babylonia and the northwest of ancient Iran. Shalmaneser also conducted extensive building work in Assur, Nineveh, and Arbela, and founded the city of Kalhu (the Biblical Calah/Nimrud).
