The idea of Ujamaa emerged from the writing and speeches of Tanzania’s first president, Julius K Nyerere, from the late 1950s and into the 1960s. Usually translated as “familyhood,” it was a form of African socialism that blended broadly conceived socialist principles with a distinctly “communitarian” understanding of African societies, and a strong commitment to egalitarian societies. It was to form the bedrock of efforts to institute profound social change from the late 1960s, directed and shaped by the state. At the heart of the idea of Ujamaa were ideas around self-reliance (people should build for themselves their futures), total participation of all in developing the nation (“nation building,” and self-help), communal labor in the rural sector and communal ownership of land, and nationalizations in the private sector and of public services. Ujamaa as an idea was to have a profound impact on Tanzanian economic and development policies from the late 1960s, but also had a wider continental impact in contributing to and shaping a distinctive form of African socialism in the 1960s and 1970s.
