What “Babylonian” covers
Babylon was a city on the Euphrates in what is now central Iraq, south of modern Baghdad. “Babylonian” can mean the city, the kingdom ruled from it, or the wider culture of southern Mesopotamia that lasted for well over a thousand years. It is worth keeping these apart, because Babylon was a great power in only two stretches of its history, separated by long centuries when it was respected as a religious and scholarly centre but did not dominate its neighbours.
The culture itself grew out of the older Mesopotamian civilization of the Sumerians and Akkadians. Babylonians inherited its writing, its gods, its schools and its habit of recording almost everything on clay. They changed and extended all of these, and later peoples, from Assyrians to Persians to Greeks, inherited them in turn.
Two phases of power
The first phase is the Old Babylonian period. Kings of an Amorite dynasty ruled Babylon from about 1894 BCE (dates here follow the commonly used “middle chronology”, and scholars debate shifts of several decades). The sixth ruler, Hammurabi (reigned about 1792 to 1750 BCE), united most of southern Mesopotamia and reached up the Euphrates. His kingdom shrank under his successors, and the dynasty ended when a Hittite raid struck Babylon around 1595 BCE. “Empire” is a generous word for this phase; it is better described as a large regional kingdom.
Babylon then spent roughly four centuries under the Kassite dynasty, a period of stability in which Babylonian became a language of international diplomacy. Later it was fought over, and sometimes ruled directly, by the Assyrian Empire.
The second phase is the Neo-Babylonian or Chaldean empire. Nabopolassar took the throne in 626 BCE and helped to destroy Assyria. His son Nebuchadnezzar II (reigned 605 to 562 BCE) ruled territory from the Persian Gulf region to the Mediterranean coast. The state fell to the Persian king Cyrus in 539 BCE, so this true empire lasted under ninety years.
Language and writing
Babylonian was a dialect of Akkadian, a Semitic language that is not related to Sumerian. Scholars speak of Old, Middle, Neo- and Late Babylonian as the language changed. Sumerian survived as a learned and liturgical language, much as Latin did in medieval Europe, and scribes trained by copying Sumerian word lists and literary texts.
Both languages were written in cuneiform writing, wedge-shaped signs pressed into wet clay. From the first millennium BCE, Aramaic, written in a simple alphabet on perishable materials like leather and papyrus, became widespread in daily life across the Near East. Cuneiform did not vanish, though. Temples kept using it, and the latest datable cuneiform text is an astronomical almanac from about 75 CE.
Society
The best-known social description comes from the laws of Hammurabi, which distinguish three broad groups: the awilu, free men of standing; the muskenu, a dependent or lower-status group whose exact meaning scholars still discuss; and slaves. Penalties and compensation in that text vary with rank. The same law collection shows that married women could hold a dowry and, in some circumstances, property. Women also took on religious roles. At Sippar, for example, the naditu were women dedicated to the sun god Shamash who lived in a cloister-like compound and often managed family land.
Most people farmed, herded or worked for a temple or palace. Family households were the basic unit, and adoption, inheritance and marriage are all well documented in contracts.
Economy
Babylonia’s wealth rested on irrigated agriculture. Canals drawn from the Euphrates watered barley fields and date palm groves, a system inherited from the Sumerians. Sheep produced wool, and temples and palaces held large estates and employed dependent workers. Traders moved goods along the rivers and across the desert to the Levant and the Gulf.
Silver, weighed out rather than coined, served as the standard of value. Contracts record loans, sales of land, partnerships and dowries. In the Neo-Babylonian and Persian periods, family firms such as the Egibi of Babylon left archives showing a sophisticated business world, which later writers sometimes describe as an early form of ancient banking, though they were private merchant houses rather than banks in the modern sense.
Religion, learning and craft
Marduk, the city god, rose to become the leading god of Babylonia. His temple Esagila and the stepped tower Etemenanki stood at the heart of the city. The New Year festival, the Akitu, held in the spring month of Nisan, celebrated Marduk and the renewal of kingship. Babylonian religion was polytheistic, and temples were also centres of economy, writing and science.
Babylonian scholars built a body of mathematics based on the sexagesimal number system, which still shapes how we divide hours and angles. Surviving school tablets show that scribes solved quadratic-type problems and calculated with tables of reciprocals. Another strength was astronomy: Babylonian astronomy produced centuries of systematic sky records, and scholars also compiled long omen lists and medical texts.
Babylon under Nebuchadnezzar II
Nebuchadnezzar rebuilt Babylon on a grand scale. Brick inscriptions record his work on temples, palaces and city walls. The Ishtar Gate, faced with glazed blue brick and decorated with animals, opened onto a processional street used in religious festivals. The German archaeologist Robert Koldewey excavated much of this Neo-Babylonian city from 1899 onward.
The Hanging Gardens are often attached to this king, but no cuneiform text mentions them, and Greek writers who described them wrote centuries later. Their existence and location remain debated, and they are best treated as a tradition rather than a confirmed feature of the city.
How we know
Our sources include thousands of clay tablets: royal inscriptions, letters, legal and business archives, scholarly texts and the Babylonian Chronicles, which record events year by year. Greek authors such as Herodotus and the Bible add outside perspectives, though both need careful handling, since they describe Babylon as foreign observers. Much of ancient Babylon lies under high groundwater or in unexcavated mounds, so what we know reflects what happened to survive and be found.
