Gajaaga, also known as Galam, was a Soninke kingdom on the upper Senegal River in West Africa that existed from before 1000 CE to 1858. The kingdom was mainly located in present-day Senegal and some parts of Mali. It was sometimes referred to as the Land of Gold, which it exported in large quantities, and 'Galam' in fact means "gold" in Wolof. In the middle of the 17th century, Gajaaga was perhaps the most powerful state in the upper Senegal River region. It controlled both banks of the river from the area of Kayes downstream to Bakel.
