Middle Assyrian Empire in the context of "Bronze Age collapse"

The Hittites (/ˈhɪtaɪts/) were an Anatolian Indo-European people who formed one of the first major civilizations of the Bronze Age in West Asia. Possibly originating from beyond the Black Sea, they settled in modern-day Turkey in the early 2nd millennium BC. The Hittites formed a series of polities in north-central Anatolia, including the kingdom of Kussara (before 1750 BC), the Kanesh or Nesha Kingdom (c. 1750–1650 BC), and an empire centered on their capital, Hattusa (around 1650 BC). Known in modern times as the Hittite Empire, it reached its peak during the mid-14th century BC under Šuppiluliuma I, when it encompassed most of Anatolia and parts of the northern Levant and Upper Mesopotamia, bordering the rival empires of the Hurri-Mitanni and Assyrians.

Between the 15th and 13th centuries BC, the Hittites were one of the dominant powers of the Near East, coming into conflict with the New Kingdom of Egypt, the Middle Assyrian Empire, and the Empire of Mitanni. By the 12th century BC, much of the Hittite Empire had been annexed by the Middle Assyrian Empire, with the remainder being sacked by Phrygian newcomers to the region. From the late 12th century BC, during the Late Bronze Age collapse, the Hittites splintered into several small independent states, some of which survived until the eighth century BC before succumbing to the Neo-Assyrian Empire; lacking a unifying continuity, their descendants scattered and ultimately merged into the modern populations of the Levant and Mesopotamia.

Assyria was a major ancient Mesopotamian civilization that existed as a city-state from the 21st century BC to the 14th century BC and eventually expanded into an empire from the 14th century BC to the 7th century BC.

Spanning from the early Bronze Age to the late Iron Age, modern historians typically divide ancient Assyrian history into the Early Assyrian (c. 2600–2025 BC), Old Assyrian (c. 2025–1364 BC), Middle Assyrian (c. 1363–912 BC), Neo-Assyrian (911–609 BC), and post-imperial (609 BC–c. AD 240) periods, based on political events and gradual changes in language. Assur, the first Assyrian capital, was founded c. 2600 BC, but there is no evidence that the city was independent until the collapse of the Third Dynasty of Ur, in the 21st century BC, when a line of independent kings starting with Puzur-Ashur I began ruling the city. Centered in the Assyrian heartland in northern Mesopotamia, Assyrian power fluctuated over time. The city underwent several periods of foreign rule or domination before Assyria rose under Ashur-uballit I in the early 14th century BC as the Middle Assyrian Empire. In the Middle and Neo-Assyrian periods, Assyria was one of the two major Mesopotamian kingdoms, alongside Babylonia in the south, and at times became the dominant power in the ancient Near East. Assyria was at its strongest in the Neo-Assyrian period, when the Assyrian army was the strongest military power in the world and the Assyrians ruled the largest empire then yet assembled in world history, spanning from parts of modern-day Iran in the east to Egypt in the west.

The Neo-Assyrian Empire was the fourth and penultimate stage of ancient Assyrian history. Beginning with the accession of Adad-nirari II in 911 BC, the Neo-Assyrian Empire grew to dominate the ancient Near East and parts of South Caucasus, North Africa and Eastern Mediterranean throughout much of the 9th to 7th centuries BC, becoming the largest empire in history up to that point. Because of its geopolitical dominance and ideology based in world domination, the Neo-Assyrian Empire has been described as the first world empire in history. It influenced other empires of the ancient world culturally, administratively, and militarily, including the Neo-Babylonians, the Achaemenids, and the Seleucids. At its height, the empire was the strongest military power in the world and ruled over all of Mesopotamia, the Levant and Egypt, as well as parts of Anatolia, Arabia and modern-day Iran and Armenia.

The early Neo-Assyrian kings were chiefly concerned with restoring Assyrian control over much of northern Mesopotamia, eastern Anatolia and Levant, since significant portions of the preceding Middle Assyrian Empire (1365–1050 BC) had been lost during the late 11th century BC. Under Ashurnasirpal II (r. 883–859 BC), Assyria once more became the dominant power of the Near East, ruling the north undisputed. Ashurnasirpal's campaigns reached as far as the Mediterranean, and he oversaw the transfer of the imperial capital from the traditional city of Assur to the more centrally located Kalhu (later known as Calah in the Bible and Nimrud to the Medieval Arabs) The empire grew even more under Ashurnasirpal's successor Shalmaneser III (r. 859–824 BC), though it entered a period of stagnation after his death, referred to as the "age of the magnates". During this time, the chief wielders of political power were prominent generals and officials, and central control was unusually weak. This age came to an end with the rule of Tiglath-Pileser III (r. 745–727 BC), who re-asserted Assyrian royal power and more than doubled the size of the empire through wide-ranging conquests. His most notable conquests were Babylonia in the south and large parts of the Levant. Under the Sargonid dynasty, which ruled from 722 BC to the fall of the empire, Assyria reached its apex. Under Sennacherib (r. 705–681 BC), the capital was transferred to Nineveh, and under Esarhaddon (r. 681–669 BC) the empire reached its largest extent through the conquest of Egypt. Despite being at the peak of its power, the empire experienced a swift and violent fall in the late 7th century BC, destroyed by a Babylonian uprising and an invasion by the Medes. The causes behind how Assyria could be destroyed so quickly continue to be debated among scholars.

The king of Assyria (Akkadian: Iššiʾak Aššur, later šar māt Aššur) was the ruler of the ancient Mesopotamian kingdom of Assyria, which was founded in the late 21st century BC and fell in the late 7th century BC. For much of its early history, Assyria was little more than a city-state, centered on the city Assur, but from the 14th century BC onwards, Assyria rose under a series of warrior kings to become one of the major political powers of the Ancient Near East, and in its last few centuries it dominated the region as the largest empire the world had seen thus far. Ancient Assyrian history is typically divided into the Old, Middle and Neo-Assyrian periods, all marked by ages of ascendancy and decline.

The ancient Assyrians did not believe that their king was divine himself, but saw their ruler as the vicar of their principal deity, Ashur, and as his chief representative on Earth. In their worldview, Assyria represented a place of order while lands not governed by the Assyrian king (and by extension, the god Ashur) were seen as places of chaos and disorder. As such it was seen as the king's duty to expand the borders of Assyria and bring order and civilization to lands perceived as uncivilized. As Assyria expanded, its rulers gradually adopted grander and more boastful titles. Early kings used Iššiʾak Aššur (representative/viceroy of Ashur), considering the god Ashur to be the true king. From the time of Ashur-uballit I (14th century BC), the rulers instead used king (šar). In time, further titles, such as "king of Sumer and Akkad", "king of the Universe" and "king of the Four Corners of the World", were added, often to assert their control over all of Mesopotamia.

Ashur-uballit I (Aššur-uballiṭ I), who reigned between c. 1363 and c. 1328 BC, was the first king of the Middle Assyrian Empire. After his father Eriba-Adad I had broken Mitanni influence over Assyria, Ashur-uballit I's defeat of the Mitanni king Shuttarna III marks Assyria's ascendancy over the Hurri-Mitanni Empire, and the beginning of its emergence as a powerful empire. Later on, due to disorder in Babylonia following the death of the Kassite king Burnaburiash II, Ashur-uballit established Kurigalzu II on the Babylonian throne, in the first of what would become a series of Assyrian interventions in Babylonian affairs.

Ashur-Dan II (Aššur-dān) (934–912 BC), son of Tiglath Pileser II, was the last king of the Middle Assyrian Empire, that contributed to the efforts that led to the birthing of the Neo-Assyrian Empire. He was best known for recapturing previously held Assyrian territory and restoring Assyria to its natural borders, from Tur Abdin (southeast Turkey) to the foothills beyond Arbel (Iraq). The reclaimed territory through his conquest was fortified with horses, ploughs, and grain stores. His military and economic expansions benefited four subsequent generations of kings that replicated his model.
