Lipit-Ishtar (Lipit-Eshtar), was the fifth ruler of the first dynasty of Isin, and ruled from around 1934 BCE to 1924 BCE. Some documents and royal inscriptions from his time have survived, but he is mostly known because Sumerian language hymns written in his honor, as well as a legal code written in his name (preceding the famed Code of Hammurabi by about 200 years), were used for school instruction for hundreds of years after his death.http://en.wikipedia.org/wiki/Lipit-Ishtar
