The study of Central and Lower Mesopotamia has long been given priority over neighboring regions. Archaeological sites in Central and Lower Mesopotamia—notably Girsu but also Eshnunna, Khafajah, Ur, and many others—have been excavated since the 19th century. These excavations have yielded cuneiform texts and many other important artifacts. As a result, this area was better known than neighboring regions, but the excavation and publication of the archives of Ebla have changed this perspective by shedding more light on surrounding areas, such as Upper Mesopotamia, western Syria, and southwestern Iran. These new findings revealed that Lower Mesopotamia shared many socio-cultural developments with neighboring areas and that the entirety of the ancient Near East participated in an exchange network in which material goods and ideas were being circulated.
