But Elamite influence in southern Mesopotamia did not last. Around 1760 BC, Hammurabi drove out the Elamites, overthrew Rim-Sin of Larsa, and established a short lived Babylonian Empire in Mesopotamia. Little is known about the latter part of this dynasty, since sources again become sparse with the Kassite rule of Babylon (from c. 1595). Many archaeological finds suggest that maritime trade along the shores of Africa and Asia started several millennia ago. Trade between the Indus Valley Civilization and the cities of Mesopotamia and Elam, can be inferred from numerous find of Indus artifacts, particularly in the excavation as Susa. Various objects made with shell species that are characteristic of the Indus coast, particularly "Trubinella Pyrum" and "Fasciolaria Trapezium", have been found in the archaeological sites of Mesopotamia and Susa dating from around 2500–2000 BCE. Carnelian beads from the Indus were found in Susa in the excavation of the tell of the citadel. In particular, carnelian beads with an etched design in white were probably imported from the Indus Valley, and made according to a technique of acid-etching developed by the Harappans. Exchanges seem to have waned after 1900 BC, together with the disappearance of the Indus valley civilization. The Middle Elamite period began with the rise of the Anshanite dynasties around 1500 BC. Their rule was characterized by an "Elamisation" of Susa, and the kings took the title "king of Anshan and Susa". While the first of these dynasties, the Kidinuids continued to use the Akkadian language frequently in their inscriptions, the succeeding Igihalkids and Shutrukids used Elamite with increasing regularity. Likewise, Elamite language and culture grew in importance in Susiana. The Kidinuids (c. 1500 – 1400) are a group of five rulers of uncertain affiliation. They are identified by their use of the older title, "king of Susa and of Anshan", and by calling themselves "servant of Kirwashir", an Elamite deity, thereby introducing the pantheon of the highlands to Susiana. The city of Susa itself is one of the oldest in the world dating back to around 4200 BC. Since its founding Susa was known as a central power location for the Elamites and for later Persian dynasties.
