Erishum I

Ilu-shuma was succeeded by another powerful king, the long-reigning Erishum I (1973–1934 BC) who is notable for one of the earliest examples of written legal codes and introducing the limmu (eponym) lists that were to continue throughout Assyrian history. He is known to have greatly expanded Assyrian trading colonies in Anatolia, with twenty-one being listed during his reign. These Karum traded in: tin, textiles, lapis lazuli, iron, antimony, copper, bronze, wool, and grain, in exchange for gold and silver. Erishum also kept numerous written records and conducted major building works in Assyria, including the building of temples to Ashur, Ishtar, and Adad.
