Джемдет-Наср
The importance of the findings at Jemdet Nasr were immediately recognized after the 1920s excavations. During a large conference in Baghdad in 1930, the Jemdet Nasr period was inserted into the Mesopotamian chronology between the Uruk period and the Early Dynastic period, with Jemdet Nasr being the eponymous type site. Since then, the assemblage characteristic for the Jemdet Nasr period has been attested at other sites in south–central Iraq, including Abu Salabikh, Fara, Nippur, Ur and Uruk. The period is now generally dated to 3100–2900 BC.
