It was the first prosperous Islamic trade center in North Africa. There followed the first discoveries in the Atlantic: Madeira and the Azores, which led to the first colonization movements. Throughout the 15th century, Portuguese explorers sailed the coast of Africa, establishing trading posts for several common types of tradable commodities at the time, ranging from gold to slaves, as they looked for a route to India and its spices, which were coveted in Europe. The Treaty of Tordesillas, intended to resolve the dispute that had been created following the return of Christopher Columbus, was signed on 7 June 1494, and divided the newly discovered lands outside Europe between Portugal and Spain along a meridian 370 leagues west of the Cape Verde islands (off the west coast of Africa). In 1498, Vasco da Gama reached India and brought economic prosperity to Portugal and its population of 1.7 million residents.
