The Colonial Development and Welfare Act of 1940 represented a decisive departure from the earlier assumption that each British colony should support itself economically. The measure made up to £5 million a year available in loans or grants to the dependent empire. Although the policy remained embedded in colonial rule, it acknowledged that metropolitan government had a greater responsibility for development and welfare than earlier financial arrangements had allowed.

The Act had important pre-war roots. The Colonial Office had discussed the measure before the outbreak of war, and Britain had already made funds available under the Colonial Development Act of 1929. That earlier provision allowed up to £1 million a year, primarily to stimulate the British economy, and did not substantially alter the expectation that colonies should remain economically self-supporting.

Wartime circumstances helped transform an administrative proposal into a broader political commitment. The recommendations of Lord Moyne concerning disturbances in the West Indies and the ideological requirements of war against Nazi Germany helped move the Treasury away from its habitual parsimony. In Nigeria, Governor Sir Bernard Bourdillon presented the Act to the Legislative Council as a development of the utmost importance and indicated that the doctrine of colonial self-sufficiency was now dead.

The Colonial Development and Welfare Act introduced a more expansive conception of the colonial state’s responsibilities. Economic planning was no longer limited to projects immediately serving import-export commerce; development programmes also included education, medical provision, and social welfare. In British territories, this approach gave public policy a broader administrative and developmental scope than earlier colonial practice.

The act was not simply an altruistic measure. It emerged from the realisation that colonial neglect could lead to colonial disaster, a lesson associated here with the Caribbean riots of 1938. At the same time, economic development schemes were understood to benefit the metropolitan economy by increasing the surplus extracted from colonial economies and expanding markets for manufactured exports.

Nigeria provides an explicit setting for the act’s new policy language. Captain J. R. Mackie, Director of Agriculture, later described Sir Bernard Bourdillon’s statement on economic development policy in Nigeria after the act as unprecedented in public official discussion during his nearly twenty years of service there. The passage presents the act as both a welfare initiative and an instrument of imperial economic management.
