Babylonian History: Kingdoms, Empires and Foreign Rule
Babylonia was the southern Mesopotamian country around the lower Tigris and Euphrates, in present-day Iraq. Babylon gave the region its name, but it shared the landscape with older cities, including Ur, Uruk and Nippur. Irrigated fields, temples and urban households supported these communities through repeated changes of ruler. Political unity was intermittent: a king might control much of the southern plain in one generation, while his successors governed a smaller territory.
Three periods provide the principal framework for Babylonian political history. The first dynasty, conventionally dated to about 1894–1595 BCE, made Babylon a major regional power under Hammurabi. Kassite kings later consolidated a long-lived kingdom, ending around 1155 BCE. Much later, the Neo-Babylonian empire of 626–539 BCE ruled beyond Mesopotamia before Cyrus II incorporated it into the Persian Empire. These periods were separated by changes of dynasty, territorial losses and foreign intervention. The continued use of Babylonian languages and learned traditions after 539 BCE belongs to the history of communities under new rulers.
Dates in the early second millennium BCE depend on competing chronological reconstructions. The dates used here follow the conventional Middle Chronology, which places Hammurabi’s reign in 1792–1750 BCE and the end of the first dynasty in 1595 BCE. The historical sequence is firmer than every absolute year.
The first dynasty and the Old Babylonian kingdoms
Babylon rose in a landscape of competing kingdoms. Isin, Larsa, Eshnunna and Mari controlled different cities, agricultural districts and routes. Their rulers made alliances, exchanged envoys and sought help against rivals. Such diplomacy could support a king’s expansion, but cooperation was contingent on each partner’s interests. A letter from Mari describes Rim-Sin of Larsa offering troops if Hammurabi faced an attack from another country, while expecting assistance in return. Hammurabi later defeated Larsa, incorporating its territory into his own kingdom in 1763 BCE.
Conquest gave the king access to land, produce and labour, together with responsibility for a larger network of cities. Written orders connected the palace to local officials. Hammurabi instructed Sin-iddinam to organize the clearing of the Euphrates channel as far as Larsa and Ur. Removing vegetation and accumulated silt helped water reach downstream communities. Other instructions concerned diverting floodwater into marshes. These were practical tasks involving supervisors and workers, and they also expressed the ruler’s claim to sustain the country’s prosperity.
Royal justice formed another part of that claim. The monument now called the Code of Hammurabi presents the king before Shamash, the sun god associated with justice, and records conditional rulings about property, work, family relationships and injury. Its provisions connect rights with responsibilities: negligent irrigation could require compensation, while some service land supported a soldier and his household on condition that military duty continued. Contracts and judgments from everyday transactions supply a different view of how people established claims and resolved disputes.
Hammurabi’s territorial unity did not endure. Under his son Samsu-iluna, the kingdom lost control of the south, where Sealand rulers established their own authority. Southern urban communities experienced disruption, while the reduced kingdom around Babylon continued to issue contracts, administer resources and commemorate royal building work. A Hittite expedition eventually sacked Babylon in the sixteenth century BCE, conventionally in 1595. The first dynasty ended, but the consolidation of a successor kingdom took time.
Kassite rule and the changing middle Babylonian kingdom
Kassite rulers established a durable kingdom over much of Babylonia during the following centuries. Their early consolidation is poorly dated, but by the fifteenth century BCE their authority extended across the southern country. They founded Dur-Kurigalzu as a royal centre, supported traditional sanctuaries and used Akkadian for government while maintaining Sumerian learning in scholarly and religious settings.
Agriculture and institutional administration were central to the kingdom. The extensive tablets from Nippur record deliveries, assignments and groups of workers under officials. Such records show how administrators organized productive resources and accounted for their use. Kings also rewarded temples and prominent people with land or privileges. Stone monuments often called kudurrus recorded grants, exemptions and the divine powers invoked to protect them. Their inscriptions concern enforceable claims over resources.
Babylonia also participated in the diplomacy of the major Late Bronze Age kingdoms. Letters between Babylonian kings and Egyptian pharaohs discuss marriage, gifts, envoys and the treatment owed to rulers of comparable standing. Burna-Buriash II complained to Akhenaten that a gift of gold was smaller than expected and of poor quality. The complaint concerned both useful material and the honour conveyed by a royal exchange. Marriages could connect dynasties, while diplomatic equality remained something rulers asserted and negotiated.
Relations with Assyria and Elam became increasingly consequential. Assyrian intervention could determine who held the Babylonian throne, and the Assyrian king Tukulti-Ninurta I conquered Babylon in the thirteenth century BCE. Later Elamite attacks removed rulers and carried monuments away. Kassite rule ended around 1155 BCE. Subsequent Babylonian dynasties continued the country’s history, including the reign of Nebuchadnezzar I, whose campaign against Elam belongs to the twelfth century BCE, centuries before his better-known namesake Nebuchadnezzar II.
The Neo-Babylonian empire and Persian conquest
During the first millennium BCE, Babylonian rulers and communities faced recurring Assyrian domination. Babylon’s religious importance made control of the city politically valuable, but relations could be violent. Sennacherib destroyed Babylon in 689 BCE; his successor Esarhaddon sponsored its restoration. The Neo-Babylonian state emerged when Nabopolassar established himself as king in 626 BCE. His forces and their Median allies helped bring down the Assyrian Empire, including the capture of Nineveh in 612.
Nebuchadnezzar II, who reigned in 605–562 BCE, extended Babylonian power into the Levant. Campaigns imposed tribute, replaced rulers and brought captives into Babylonia. Jerusalem submitted in 597 BCE and was destroyed after another rebellion in 587 or 586. Deportation transferred people with agricultural, craft and administrative skills into the imperial heartland. The later documents from Yahudu, a settlement whose name means Judah, record Judean families cultivating land and meeting obligations in Babylonia.
Imperial resources also supported monumental construction. Babylon’s walls, palaces and ceremonial routes joined defensive needs with royal display. The blue glazed bricks and divine animals of the Ishtar Gate made a city entrance part of the religious landscape. Temples remained major landholders, employers and recipients of offerings. Their archives, together with those of private families, reveal rents, credit, production and the organization of property behind the empire’s public monuments.
After Nebuchadnezzar’s death, several short reigns preceded Nabonidus’s accession in 556 BCE. Nabonidus spent years at Tayma in Arabia, while his son Belshazzar exercised authority in Babylonia. The king’s absence affected the New Year ceremonies that required his participation, although temple offerings continued. In 539 BCE, Cyrus defeated Babylonian forces near Opis and took the cities of Sippar and Babylon. Babylon became part of the Persian Empire.
Persian rule altered the political framework while retaining many local institutions and forms of record keeping. Alexander entered Babylon in 331 BCE, and the city subsequently passed into Hellenistic and later Parthian settings. Scholars continued to copy literature, observe the sky and calculate celestial events. Those activities preserved and developed Babylonian learning long after an independent Babylonian empire had ceased to exist.
