Hittites
Hattusilis I united the Hattic kingdoms and founded the Hittite Kingdom. Later kings gradually conquered surrounding regions. The Empire reaches its greatest extent with the conquests of Suppiluliuma I who defeated Arzawa and Mitanni. Muwatalli defended Hittite gains in Syria against the Egyptians, inflicting a defeat on the Egyptians in a massed chariot battle at Kadesh. Hattusili III made peace with Egypt and contended with the Kaska invaders and Achaian adventurers as well as the rising power of Assyria. Later kings extended Hittite rule over Cyprus. The Empire ultimately fell to Kaska, Phrygian and sea People invasions. Hittite Carchemish and other successor kingdoms survived much longer to defy the Assyrians.
The Hittites fought other Anatolian kingdoms, notably Arzawa, the Hurrian empire of Mitanni, Babylon, Assyria, Egypt, the Kaska tribes, the Lukka pirates, Achaians, Cypriots, Syrians and had civil wars.
