Between the 15th and 13th centuries BC, the Empire of Hattusa, conventionally called the Hittite Empire, came into conflict with the New Kingdom of Egypt, the Middle Assyrian Empire and the empire of the Mitanni for control of the Near East. The Middle Assyrian Empire eventually emerged as the dominant power and annexed much of the Hittite Empire, while the remainder was sacked by Phrygian newcomers to the region. After c. 1180 BC, during the Late Bronze Age collapse, the Hittites splintered into several independent Syro-Hittite states, some of which survived until the eighth century BC before succumbing to the Neo-Assyrian Empire.
