There are two groups of people in this excerpt: the Mesopotamians and the Guti. Guti was a Sumerian name for people who lived in the mountains and who did not worship the Mesopotamian gods. The Guti invaded Mesopotamia. The authors of this document were several Mesopotamian people (probably priests at the holy city of Nippur) who wrote parts of this source around 2000 BCE, and an unknown Mesopotamian scribe, who copied the parts into one document around 1800 BCE. Written in the Sumerian language, the document was propaganda against a king from an earlier time, Naram-Sin.
