Julius Nyerere did not want Tanzanian socialism to look like a translation of a European text. Ujamaa, the Kiswahili word for familyhood, was his attempt to build a socialist politics out of what he held to be an authentically African ethic rather than an imported one: the mutual obligation he believed had organized precolonial African village life before colonialism replaced it with the individualism of the market and, in his reading, the class antagonism of European Marxism. Set out in the 1967 Arusha Declaration, Ujamaa called for communal ownership of property, mutual obligation between members of a community, and national self-reliance, an explicit rejection of the aid dependency Nyerere believed had left newly independent African states beholden to their former colonizers in a different form.
The doctrine's legitimacy claim followed directly from that founding distinction. Where capitalism, in Nyerere's account, justified political authority through the protection of individual property and where European Marxism justified it through representing an industrial working class Tanzania barely had, Ujamaa justified authority through its capacity to express and enlarge familyhood itself: a government ruled legitimately when its policies deepened the same mutual obligation Nyerere held bound an African village together. That claim gave Ujamaa its distinctive institutional expression, villagization, in which rural Tanzanians were organized into planned communal villages the state could reach with clean water, health care, and agricultural extension services that scattered homesteads made prohibitively expensive to serve.
Villagization ultimately touched close to ten million people, one of the largest rural social engineering programs attempted anywhere in postcolonial Africa, and it left real, lasting gains in health, education and the spread of Kiswahili as a genuinely national language across a country with well over a hundred distinct ethnic groups. Nyerere's own account of Ujamaa rested on voluntary participation, but voluntary participation fell well short of what the policy needed, and by the mid 1970s compulsion had replaced persuasion across large parts of rural Tanzania: farmers were required, not invited, to relocate, and agricultural production fell as a result. Familyhood as a philosophy of legitimate authority proved easier to articulate than to implement without the coercion it had explicitly been designed to avoid.
