International relationships are an integral part of understanding human interaction at the global level. These connections occur primarily through politics, economics, territorial expansion, and warfare, parallel to the way that ancient societies often came into contact with one another. Specifically, the international relationship between the ancient civilizations of Egypt and Nubia can be understood under these terms. This project will examine how Egypt interacted with Nubia in reference to the Semna boundary stela of Senwosret III and the border fortresses established along the southern Egyptian-Nubian border. The analyzation of the foreign policy enacted by Senwosret III, how it affected both the Egyptians and the Nubians, and the strategic placement of the fortresses contribute to an overall theme of international affairs in the ancient world. The Semna boundary stela provides the greatest insight into the mind of the Egyptians and, thus, is translated from Middle Egyptian into transliterations and then into English within the body of this text. With extensive research into ancient Egyptian history, politics, and defensive procedures, the significance of Egypt’s relationship with Nubia shapes the pattern of communication between Egypt and most of its foreign neighbors. The research concludes that Egypt, acting as an agent of power during the Middle Kingdom, saw themselves as a superior nation worthy of dominating the other minor civilizations that existed within their network.
