There is little known about the early history of the area. By about 1000 AD the Soninke, Mandinka and Fula peoples had formed settlements along the Gambia River. The Toucouleur people were settled in east and central Senegal. Kingdoms such as the Jolof and the Sere settled in the area north of the Gambia River. The first Europeans, Portuguese sailors, arrived about 1455. Portugal controlled the area between the Sénégal and Gambia Rivers until the British, Dutch and French moved into the area. They traded goods such as salt, iron, guns and gunpowder for gold, ivory, ebony and slaves.
