The most famous Babylonian kings include Hammurabi, who transformed Babylon into a major regional power in the 18th century BCE, Nebuchadnezzar II, who expanded the Neo-Babylonian Empire and rebuilt Babylon on a monumental scale, and Nabonidus, the last king of independent Babylon before Cyrus the Great conquered the city in 539 BCE.

Babylonian Kings Timeline
The history of the kings of Babylon spans several different dynasties and periods. Babylon was not continuously an independent empire for two thousand years; its political importance changed repeatedly as different rulers and foreign powers controlled Mesopotamia.
c. 1894 BCE — Babylonian Dynasty Begins
The First Dynasty of Babylon traditionally begins with Sumu-abum, who established Babylon as an independent kingdom.
At this stage, Babylon was still one of several competing city-states in southern Mesopotamia. Its later prominence would come through the expansion of its territory and the achievements of its kings.
c. 1792 BCE — Hammurabi Becomes King
Hammurabi became king of Babylon around 1792 BCE.
During his long reign, he gradually defeated rival kingdoms and transformed Babylon into the dominant political power in much of Mesopotamia.
His reign represents the most important stage in the rise of the Old Babylonian Empire.
c. 1760s BCE — Hammurabi Expands Babylonian Power
Hammurabi conquered or incorporated major rival states, including Larsa, Eshnunna, and Mari.
By the later part of his reign, Babylon controlled a large portion of Mesopotamia.
His political achievements established Babylon as one of the most important kingdoms of the ancient Near East.
c. 1750 BCE — Hammurabi Dies
Hammurabi died around 1750 BCE and was succeeded by his son Samsu-iluna.
Although Samsu-iluna inherited a powerful kingdom, maintaining Hammurabi’s territorial gains proved difficult.
c. 1750–1712 BCE — Reign of Samsu-iluna
Samsu-iluna ruled Babylon for several decades.
His reign was marked by rebellions and territorial losses as Babylon struggled to maintain control over the territories conquered by Hammurabi.
Despite these challenges, the Babylonian dynasty continued to rule from Babylon.
1595 BCE — Fall of the Old Babylonian Dynasty
Babylon was captured by the Hittite king Mursili I around 1595 BCE.
This event brought the Old Babylonian period to an end and was followed by the rise of the Kassite dynasty, which ruled Babylon for several centuries.
c. 1531–1155 BCE — Kassite Kings Rule Babylon
The Kassites established a long-lasting dynasty in Babylon.
Although they were not originally Babylonian in origin, they adopted Babylonian traditions and maintained Babylon as an important political and cultural center.
This period demonstrates that the history of Babylonian kings included several different dynasties rather than one continuous royal family.
1155 BCE — Kassite Dynasty Ends
The Kassite dynasty was overthrown, beginning another period of political instability and competition for control of Babylon.
Babylon continued to be an important city even when its kings did not control a large empire.
626 BCE — Nabopolassar Establishes the Neo-Babylonian Empire
Nabopolassar became king of Babylon in 626 BCE and founded the Neo-Babylonian dynasty.
He successfully rebelled against the Assyrian Empire and established Babylonian independence.
This marked the beginning of Babylon’s final major period as an imperial power.
605 BCE — Nebuchadnezzar II Becomes King
Nebuchadnezzar II succeeded Nabopolassar in 605 BCE.
He became the most powerful ruler of the Neo-Babylonian Empire and greatly expanded Babylonian influence in the Near East.
c. 605–562 BCE — Reign of Nebuchadnezzar II
Nebuchadnezzar II ruled for more than four decades.
His reign is associated with:
- expansion of the Neo-Babylonian Empire
- campaigns in the Levant
- the conquest of Jerusalem
- rebuilding projects in Babylon
- temples dedicated to Marduk
- monumental city walls and gates
Under Nebuchadnezzar, Babylon reached an extraordinary level of political and architectural importance.
562 BCE — Nebuchadnezzar II Dies
Nebuchadnezzar II died in 562 BCE.
Several relatively short reigns followed, creating a period of political instability before Nabonidus eventually became king.
556 BCE — Nabonidus Becomes King
Nabonidus became king of Babylon in 556 BCE.
He was the final king of independent Babylon and is particularly notable for his interest in ancient temples, religious traditions, and archaeological restoration.
His long absence from Babylon also became one of the distinctive features of his reign.
539 BCE — Cyrus the Great Conquers Babylon
In 539 BCE, Cyrus the Great conquered Babylon and incorporated the city into the expanding Achaemenid Persian Empire.
This ended Babylon’s political independence and brought the Neo-Babylonian period to a close.
Babylon itself remained an important city under Persian rule, but its independent line of kings had ended.
