Community development represents the synthesis of post-war British colonial development policy. Officially used for the first time in 1948, in Arthur Creech Jones’ definition community development was a movement based on the active participation and cooperation of local community members promoting a better life for the community, encompassing all forms of improvement in the areas of agriculture, public health and sanitation, infant and maternal welfare, and the spread of literacy. The main purpose of this article is not to delve into the community development projects themselves but to discuss the ways this concept was implemented, used, and promoted by Britain in two different spaces: the colonies and the United Nations. These two contexts are pivotal for the promotion of the post-war British colonial rhetoric. In the colonies, British colonial discourse pursued two intertwined goals: on the one hand, the relegitimisation of the colonial empire and, on the other, the preparation of the transition to independence in order to maintain an influence that would replace political rule and physical presence. The United Nations were used instead by the British as an arena to internationalise their colonial policy and establish their legitimisation.
