In the second millennium B.C., the Semitic language became the current and official language of Babylonia and Assyria, while Sumerian was preserved in schools and temples, and even sometimes used in an official inscription as Latin is today. The black stela of Hammurabi at Ur was inscribed both in Semitic and Sumerian. After the final destruction of Ur in the eleventh year of Samsuiluna, his successor, the Sumerian south falls into oblivion. Only letters, business documents and contracts of that period are preserved in the Babylonian Section of the University Museum.
