In recognition of the suffering of the people of the AOF territories during the war and of the AOF's contribution to the war effort of the Free French (at one time more than half the Free French forces were Africans), Free French officials convened a conference in Brazzaville, Congo, in June 1944 to propose postwar reforms of the colonial administration. The conference favored greater administrative freedom in each colony, combined with the maintenance of unity through a federal constitution. It also recommended the abolition of the indigénat and forced labor, the establishment of trade unions, the rapid extension of education, and the granting of universal suffrage.
