During the late fourth and early third millennia Bf the pristine state
of Egypt arose from a group of independent, Neolithic agricultural vi
llages. The traditional explanation of the unification of Upper and Lo
wer Egypt is that Narmer conquered the Delta. A diachronic model based
on intergroup competition suggests that a gradual coalescence of poli
ties occurred. Chiefdoms at Nagada, Thinis, and Hierakonpolis are hypo
thesized to have formed in the middle Predynastic and were then absorb
ed by the Hierakonpolis polity in the later fourth millennium. Later,
the Upper Egyptian polity absorbed the Deltaic one. If such a model is
accurate, it may be possible to identify intragroup competition at th
e level of a single polity (as weil as interpolity competition). Here,
a mortuary analysis of the large Predynastic cemetery at Naga-ed-Der
indicates that several descent groups used the facility simultaneously
. Grave inventories indicate that the different groups experienced eco
nomic trajectories consistent with a competition model. At various tim
es in the use of the cemetery, different groups displayed,greater amou
nts of wealth, and ii was derived from different sources. In the earli
est phase of the cemetery, trade was directed toward the south. In the
second phase evidence of outside trade vanishes at about the time of
the Chalcolithic collapse in the Southern Levant. In the third phase,
trade rebounds, but now it is oriented toward Syria and Mesopotamia. T
he outside contacts appear to have been an important element in elites
' gaining and justifying positions of power. The political unification
of Egypt may be the result of the efforts uf Upper Egyptian chieftain
s to control the lucrative trade routes with Southwest Asia; the creat
ion of an Egyptian state may then be seen as an unintended consequence
, in that it resulted not from the tenuous political unification forge
d putatively by Narmer, but from a series of actions throughout the fi
rst two dynasties to retain and extend economic, political, and ideolo
gical control of the Nile Valley. (C) 1997 Academic Press.
