Early Dilmun and its rulers: new evidence of the burial mounds of the elite and the development of social complexity, c. 2200-1750 BC

This paper deals with the social organisation of early Dilmun in Bahrain based on evidence from the burial mound record. Complete aerial photography survey and mapping have documented the extensive mound fields of Bahrain in their entirety and revealed a new and rare type of burial mound encircled by an outer ring wall. From the spatial distribution and appearance of these 'ring mounds' it is argued that they cover the time span 2200-1750 BC. It is further argued that the ring mounds reflect the entombment of a prominent segment of early Dilmun society and thus testify to the presence of a social elite as early as the late third millennium BC. The paper offers evidence supporting the view that fundamental changes in the size of the ring wall and the encircled mound occurred over time, culminating in the colossal 'royal' mounds near Aali village. The increase in size of the special mounds and the exclusive appearance of the type in the Aali cemetery after the emergence of ten concentrated cemeteries around 2050 BC are correlated with the already available evidence of increasing social complexity in Dilmun. Three clusters of ring mounds in Aali are argued to reflect the appearance of one or more ruling lineages that were ultimately to found the colony on Failaka, Kuwait, and rule not only Bahrain but also the adjacent coast of Saudi Arabia.
