The Urartians were one of the Hurrian tribes in Armenia. In 860, under king Aramu, they absorbed the surrounding tribes and organized a central state. Under the kings Menuas, Ishpuini, Argishti, and Sarduri II, Urartu became the strongest state in the region by conquering Kolchis, Syria, Cilicia, Lake Sevan, and the rest of Armenia. They were the main rival of Assyria until 714, when the barbaric Cimmerians crushed the Urartian army in the north. The Assyrians then invaded from the south and attacked Tushpa, the capital. The Assyrians were crushed and they turned back. The next time they invaded, they completely ignored Tushpa, saying that the Urartian cavalry was too strong. Urartu continued to deteriorate, aiding in the demise of Assyria and then, according to the Bible, were involved in an anti-Babylonian coalition. After that the Medes destroyed them and the Orontid Armenian kingdom arose from Urartu's rubble.
