Book excerpt: Colonialism and Underdevelopment in Ghana (1978) examines Ghana’s integration into the world economic system, and the effects which such integration had on its development. The time period covered coincides both with the institution of formal political control in Ghana, and with the use of that control to promote Ghana’s development as a peripheral capitalist nation, as a supplier of primary agricultural and mineral products and as a buyer of manufactured goods. 1939 is taken as the cut-off for this book as it ends the classical colonial period.
