The Code of Ur-Nammu
This is the oldest known law code surviving today. It is from Mesopotamia and is written on tablets, in the Sumerian language c. 2100–2050 BC. The prologue, typical of Mesopotamian law codes, invokes the deities for Ur-Nammu's kingship, Nanna and Utu, and decrees "equity in the land":
"…After An and Enlil had turned over the Kingship of Ur to Nanna, at that time did Ur-Nammu, son born of Ninsun, for his beloved mother who bore him, in accordance with his principles of equity and truth... Then did Ur-Nammu the mighty warrior, king of Ur, king of Sumer and Akkad, by the might of Nanna, lord of the city, and in accordance with the true word of Utu, establish equity in the land; he banished malediction, violence and strife, and set the monthly Temple expenses at 90 gur of barley, 30 sheep, and 30 sila of butter. He fashioned the bronze sila-measure, standardized the one-mina weight, and standardized the stone weight of a shekel of silver in relation to one mina... The orphan was not delivered up to the rich man; the widow was not delivered up to the mighty man; the man of one shekel was not delivered up to the man of one mina."
