Urartu re-emerged in Assyrian inscriptions in the 9th century BC as a powerful northern rival of Assyria. Following the collapse of the Hittite empire c. 1180 BC, the Phrygians, an Indo-European people, achieved ascendancy in Anatolia until their kingdom was destroyed by the Cimmerians in the 7th century BC. Starting from 714 BC, Urartu shared the same fate and dissolved in 590 BC, when it was conquered by the Medes. The most powerful of Phrygia's successor states were Lydia, Caria and Lycia.
