Sumu-abum is listed as the first ruler of Babylon’s First (Amorite) Dynasty, marking the start of the Old Babylonian royal line traditionally dated to the late 19th century BCE (Middle Chronology).
Sumu-la-El’s reign is commonly placed after Sumu-abum in the dynasty’s early expansion phase, when Babylon was still a relatively small Amorite kingdom in central Mesopotamia.
Sabium (Sabum) is placed third in the First Dynasty sequence; surviving year-names and later king lists preserve his position in the Amorite royal succession.
Apil-Sin is traditionally the fourth king of the First Dynasty; his reign falls in the early 19th–early 18th century BCE (Middle Chronology) as Babylon’s political footprint gradually widened.
Sin-muballit (Apil-Sin’s successor and Hammurabi’s father) is described in modern summaries as an early Babylonian ruler who expanded Babylon’s control beyond its initial city-state base, preceding Hammurabi’s major conquests.
Hammurabi became the sixth king of Babylon’s First Dynasty, reigning in the early-to-mid 18th century BCE (Middle Chronology) and later becoming the dynasty’s most influential ruler.
After years of rivalry, Hammurabi conquered Larsa, defeating its king Rim-Sin; this victory brought much of southern Mesopotamia under Babylonian control and was pivotal in Babylon’s rise to regional dominance.
During Hammurabi’s reign, a major royal law collection (conventionally called the Code of Hammurabi) was composed/compiled in the mid-18th century BCE, later famously preserved on a basalt stele.
Hammurabi was followed by his son Samsu-iluna; modern accounts characterize this reign as a period of revolts and contraction after Hammurabi’s rapid expansion.
Abi-eshuh (successor to Samsu-iluna) is placed in the early 17th century BCE (Middle Chronology). Later chronicles and year-name traditions associate his reign with fighting Kassite forces and efforts against the Sealand polity in the south.
Ammisaduqa’s reign is tied to the famous Venus observations later preserved as the Venus Tablet(s) of Ammisaduqa, an important dataset used in scholarly debates over Old Babylonian chronology (high/middle/low chronologies).
In the mid-16th century BCE (Middle Chronology), Hittite king Mursili I raided Babylon, an event widely treated as ending the Amorite (First) Dynasty and ushering in a period of political transition in southern Mesopotamia.
