Rim-Sin I

Rim-Sin I began his reign over Larsa, which would last 60 years, one of the longest in Mesopotamian history. His long rule allowed for sustained military campaigns and administrative consolidation, making Larsa a major power in southern Mesopotamia.

Rim-Sin I oversaw the construction of canals, temples, and city walls in Larsa and other cities under his control. These projects improved agriculture and defense, contributing to the prosperity of his kingdom during his long reign.

Rim-Sin I captured the city of Isin after a prolonged siege, ending the First Dynasty of Isin. This conquest brought most of southern Mesopotamia under Larsa's control, making Rim-Sin the dominant ruler in the region before Hammurabi's rise.

After decades of rivalry, Hammurabi of Babylon defeated Rim-Sin I and conquered Larsa. Rim-Sin was captured and likely executed, ending his long reign and incorporating Larsa into the growing Babylonian empire.
