Even though the fertile crescent civilizations are considered the oldest in history, at the time the Burney Relief was made other late Bronze Age civilizations were equally in full bloom. Travel and cultural exchange were not commonplace, but nevertheless possible. To the east, Elam with its capital Susa was in frequent military conflict with Isin, Larsa and later Babylon. Even further, the Indus Valley Civilization was already past its peak, and in China, the Erlitou culture blossomed. To the southwest, Egypt was ruled by the 12th dynasty; further to the west the Minoan civilization, centred on Crete with the Old Palace in Knossos, dominated the Mediterranean. To the north of Mesopotamia, the Anatolian Hittites were establishing their Old Kingdom over the Hattians; they brought an end to Babylon's empire with the sack of the city in 1531 BCE. Indeed, Collon mentions this raid as possibly being the reason for the damage to the right-hand side of the relief.
