“…Status differentiation markers in the form of elaborate bead working, imported ceramics or iron objects were not detected in the archaeological record from any of the middle to late Holocene sites recently tested in Tsavo. Such objects are commonly found in later sites in the deep interior of southern and eastern Africa (Fagan, 1972;Kusimba, 2003;Mutoro, 1998;O'Leary, 1984;Reid, 1990;Robertshaw, 1991bRobertshaw, , 1997Taylor et al, 2000) and on the immediate rural periphery of the Swahili Coast (Abungu and Mutoro, 1993;Chami, 1999;Kusimba, 1993Kusimba, , 1999aMutoro, 1987;Walz, 2003). In some of these cases, regional trade was an impetus for the development of local forms of status differentiation and hierarchical political organizations.…”
