This paper examines the factors and actors in Kola nut trade in the twentieth century Adamawa Emirate. Kola nut was very important in exchange in the market system of the Emirate during that time. In fact, Kola trade traversed various regions of Nigeria with some acting as suppliers while others were consumers of the product. Adamawa, especially in the ninetieth century, was both a consumer and a supplier of a variant of a kola known as Ganjigaga. The factors that influenced/inhibited kola trade in Adamawa in the twentieth century included the imposition of colonial rule which introduced colonial currency and also partitioned the kola nut producing area of the emirate. Other factors are the rise in export earnings which encouraged the production of cash crops, improved transportation and affluence among the people. The actors in the trade are mainly wholesalers and retailers of the commodity and in the 20th century Adamawa there was the predominance of Wudirawa (people from Katagum) in the trade.
