‘Chronicles of Bailundo’ is a fragmentary account of life in Bailundo, Central Angola. The manuscript, whose authorship and exact date are unknown, is available at the archives of the American Board of Commissioners for Foreign Missions (ABCFM) at Houghton Library, Harvard University. It was written in Umbundu, the vernacular spoken in Bailundo, by North American Congregational missionaries between 1903 and the 1930s. Although the source mentions no dates, it refers roughly to the period between the seventeenth century and the gradual establishment of Portuguese colonial rule and Christian missions in the late nineteenth and early twentieth centuries. It gives access to both the Umbundu then spoken in Bailundo and the perspective of Umbundu-speaking subjects on what it was like to live in this polity. The source addresses socio-cultural, political and economic aspects of life in Bailundo as well as significant historical events, such as the Bailundo War (1902–03). The text in Umbundu, published as supplementary material with this article, has been transcribed, translated into Portuguese and English, and annotated. The version published following the main introduction of the article presents an annotated sample of the source in English. The full version, published as supplementary material, comprises the complete original in Umbundu, its complete annotated translation into English, and a complete annotated translation into Portuguese. The article addresses the authorship, contents, form and context of production of the source.
