From the beginning, Welensky was involved in the creation of the Federation of Rhodesia and Nyasaland. He had earlier wanted an amalgamation of Northern and Southern Rhodesia with a constitution similar to that of Southern Rhodesia (that had effectively granted responsible government to the white Rhodesians by specifying franchise qualifications that few blacks had so far achieved - though they were not prevented from acquiring them). After the British Government rejected this idea, he set about the creation of a federation, and against his judgement, the small colony of Nyasaland was included. His main wish for amalgamation, and later federation, was primarily so the complementary economic strengths of the Rhodesias could be put to best use. He felt that the colonies were missing out on the post-war economic boom.
