The two cities of Mari and Ebla dominate the historical record for this region. According to the excavator of Mari, the circular city on the middle Euphrates was founded "ex nihilo" at the time of the Early Dynastic I period in Lower Mesopotamia. Mari was one of the main cities of the Middle East during this period, and it fought many wars against Ebla during the 24th century BC. The archives of Ebla, capital city of a powerful kingdom during the ED IIIb period, indicated that writing and the state were well-developed, contrary to what had been believed about this area before its discovery. However, few buildings from this period have been excavated at the site of Ebla itself.
