Samsu-iluna

Samsu-iluna (Amorite: Samsu-iluna or Samsu-ilūna, "The Sun (is) our god"; c. 1793 BC - c. 1712 BC) was the 7th king of the founding Amorite dynasty of Babylon. His reign is estimated from 1749 BC to 1712 BC (middle chronology), or from 1686 to 1648 BC (short chronology). He was the son and successor of Hammurabi. His reign was marked by the violent uprisings of areas conquered by his father and the abandonment of several important cities primarily in Sumer.

A number of letters sent by Samsu-iluna have been found of which 20 have been published. One is addressed to

Abban the king of Aleppo. No received letters have been found due to the modern high water table at Babylon.
