Why Africa lacked Centralized States – The Role of the Bronze Age

In a previous post we examined how the Greek Bronze Age was associated with the rise of city states and nascent urbanization. Many of these, such as Knossos, Mycenae, Pylos and Tiryns, are on every tourist schedule today with impressive ruins and ‘cyclopean walls’ (so called because they were so large that they could only have been built by the legendary Cyclops). Archaeologists have suggested a theory linking the use of bronze to political centralization. Copper and tin are both scarce and need to be traded, their supplies can be monopolized, and so can trade. This seems to have created both the incentive and the opportunity to concentrate power and develop urban centers, for example in Knossos in Crete which was the core of Minoan Greece. While the Greek Bronze Age cities were destroyed around 1200 BCE and some, like Mycenae, never re-emerged, many, such as Athens re-emerged on the same spot so the early centralization of the Bronze Age may have left a path dependent legacy.

Not every part of the world experienced a Bronze Age, however. Though some parts of Africa, like Benin, are now famous for their bronze work, in general Sub-Saharan Africa jumped right into the Iron Age without ever passing through this intermediate stage.

In contrast to copper and tin, iron is very widely spread as the great archaeologist Gordon Childe put it “cheap iron democratized agriculture and industry and warfare too”. So the jump to Iron Age technology may have impeded the development of states in Africa by making it more difficult for elite to concentrate and monopolize power. Africa never experienced the nascent period of political centralization that Europe did during the Bronze Age, perhaps also with a path dependent legacy.
