Situated at the crossroads between Northeast Africa, the Mediterranean, the Near East and the Indian Ocean, ancient Egypt was a strategic pathway that facilitated contacts and the circulation of peoples, products and ideas across these vast regions. Sometimes the monarchy took the initiative in these contacts, whereas in other cases, mobile populations, local leaders, itinerant merchants and independent individuals fulfilled such a role. Egyptian regions participated in these exchanges in distinctive ways. Hence, control over wealth flows, access to coveted goods, contacts with privileged trading partners and attracting royal support represented significant moves in their strategies. A constant tension between different political models (centralized, confederacies of cities and territories, regional kingdoms) reemerged through the millennia. This often led to the collapse of the central authority (as it happened around 2160 bc) and was inspired, at least in part, by the political impact of trading activities.
