Introduction Colonial past in African continent is widely known for its effect on economy. In fact, both the left and right wing believe that it restructured African economies. However, those in the center maintain that its impact was limited and confused. According to dependency and Marxists theories, which inclined to the left, colonial powers ensured that African economies were non-autonomous and dependent on their system of metropolitan as well as international economy. In essence, this ensured that African economies were dependent on their standards and remained vulnerable to fluctuations in prices of commodities due to over specialization. On the other hand, those on right wing emphasized progressive achievements of colonialism as well as opportunity for future growth. In this regard, it became essential to asses effects of colonialism on development of African economies. This paper will support the view that colonial development was essential phase in Africa (Jennings, 2009, p.94-111). Colonial Period Economic outcome of Colonial period in Africa was largely witnessed between c. 1945 and c. 1960. During this period, restructuring of African economies occurred in a large scale. In fact, some economies experienced complete overhaul of their pre-colonial development structures. African economies were gathering momentum during this period. Besides, statistics show that British Africa’s value of export (between 1947 and 1960) registered a huge increase from £120.1 Million to £591 Million. Moreover, French Africa’s value of export (between 1948 and 1953) also increased from $291 million to $484million. This shows a robust increase in export between these periods as well as restructuring of economy. Evidently, colonial period transformed these economies, which had previously depended on subsistence farming and barter trade. For instance, statistics show that during this period, per capita growth for Cameroon was 1.5 percent. Similarly, that of Kenya was 1.9 percent despite trouble from Mau Mau resistance. Other countries such as Senegal and Tanganyika, among others recorded even higher per capita growth in 4.4% and 3.7% respectively. Moreover, colonial development improved with annual increase in export by colonies. Apart from development and economic restructuring, Colonial period was overshadowed with constant resistance from colonies who wanted to rule themselves. For instance, Kenya had Mau Mau, among other associations that sought to take power from white settlers. This combined with other issues such as poor infrastructure, among others worked to impede colonial development. According to George Abbot, colonies were previously mandated to fund their growth from exports and self earned funds or loans attracted. However, this changed with the Britain changed its economic policy instituting a colonial development act in 1929. This was established under Joseph Chamberlain who was the then secretary of State for colonies. In essence, imperial government decided to be responsible for economic development of its numerous colonies. This was very important as it enabled colonies to gain funds for production and infrastructure development. Colonial Development The British government acquired several colonies with a population of over 80 million compared to their own, which was about 51 million. Moreover, the area covered by its colonies was v
