The Bronze Age collapse may be seen in the context of a technological history that saw the slow, comparatively continuous spread of iron-working technology in the region, beginning with precocious iron-working in what is now Romania in the 13th and 12th centuries. The cultural collapse of the Mycenaean kingdoms, the Hittite Empire in Anatolia and Syria, and the Egyptian Empire in Syria and Palestine, the scission of long-distance trade contacts and sudden eclipse of literacy occurred between 1206 and 1150 BC. In the first phase of this period, almost every city between Troy and Gaza was violently destroyed, and often left unoccupied thereafter (for example, Hattusas, Mycenae, Ugarit). The gradual end of the Dark Age that ensued saw the rise of settled Neo-Hittite and Aramaean kingdoms of the mid-10th century BC, and the rise of the Neo-Assyrian Empire. During the Early Iron Age, from 911 BC, the Neo-Assyrian Empire arose, vying with Babylonia and other lesser powers for dominance of the region, though not until the reforms of Tiglath-Pileser III in the 8th century BC, did it become a powerful and vast empire. In the Middle Assyrian period of the Late Bronze Age, Assyria had been a kingdom of northern Mesopotamia (modern-day northern Iraq), competing for dominance with its southern Mesopotamian rival Babylonia. From 1365–1076 it had been a major imperial power, rivaling Egypt and the Hittite Empire. Beginning with the campaign of Adad-nirari II, it became a vast empire, overthrowing 25th dynasty Egypt and conquering Egypt, the Middle East, and large swaths of Asia Minor, ancient Iran, the Caucasus and east Mediterranean. The Neo-Assyrian Empire succeeded the Middle Assyrian period (14th to 10th century BC). Some scholars, such as Richard Nelson Frye, regard the Neo-Assyrian Empire to be the first real empire in human history. During this period, Aramaic was also made an official language of the empire, alongside the Akkadian language. The states of the Neo-Hittite kingdoms were Luwian, Aramaic and Phoenician-speaking political entities of Iron Age northern Syria and southern Anatolia that arose following the collapse of the Hittite Empire around 1180 BC and lasted until roughly 700 BC. The term "Neo-Hittite" is sometimes reserved specifically for the Luwian-speaking principalities like Melid (Malatya) and Karkamish (Carchemish), although in a wider sense the broader cultural term "Syro-Hittite" is now applied to all the entities that arose in south-central Anatolia following the Hittite collapse – such as Tabal and Quwê – as well as those of northern and coastal Syria.
