Resumen
Between the 11th and the 16th centuries AD, the south-eastern half of the Horn of Africa was home to a number of Muslim stateswhich extended their authority over very diverse geographical and ethnically regions, providing stability for trade and challenging thepowerful Christian kingdom of Abyssinia to the north. They also acted as one the key actors of the international trade which connectedthe interior of Africa with the Mediterranean region, Middle East and Asia. Based on the six years of research of the SpanishArchaeological Mission in Somaliland, this paper will explore the archaeological evidences of the diverse ethnic groups, religionsand lifestyles which inhabited these Muslim medieval kingdoms, and the ways in which these communities interacted among themand with the state structures. Using the example of nomads, urban dwellers and foreign merchants in western Somaliland, it willpresent an interpretation of how these interactions could have taken place, from the trading posts of the Somaliland coast to theagriculture-based settlements of inner Somaliland, as well as the elusive but widespread nomadic archaeology. It will also analyzethe processes of emergency and consolidation of states throughout the Horn of Africa, both in the Somali region and the Ethiopianhighlands, and the role they played in regional and international contexts during the Middle Ages and Modern Ages.
