To this day research in pre-colonial Swahili history has only taken casual notice of the role of Swahili crafts. This applies in particular to blacksmithing and iron smelting. Probably iron smelting were among the driving factors of cultural contact and of the development of economical structures on the Swahili Coast. Kusimba postulates that metallurgy played an important role for cultural change within Swahili polities. Foreign trade in iron products to other parts of the Indian Ocean fostered local exchange systems that linked the East African settlements on the Coast to each other and the interior (1996:387). In this article the potential of linguistic research on iron crafts for Swahili historiography will be demonstrated, though it has to be emphasised that linguistic evidence is as of yet too scarce to allow more than preliminary results. Two steps are deemed necessary to achieve this aim. In a first step the scientific contributions by historical linguistics, history, and archaeology in regard to Swahili iron working will be reviewed. In a second step it will be demonstrated that historical semantics, together with language geography can make a significant contribution to this discussion. More than anything else, it is the semantic aspect of language that is capable of revealing pre-colonial cultural change in Africa. With comparative phonological and morphological methods historical genetic relationships within a given language family can be discovered.
