This article uses a series of love letters exchanged between an African Anglican priest and a teacher-in-training before their marriage to investigate the relationship between the fashioning of the individual self, marriage, and community at the dawn of Tanganyika's independence. When seen through marriage's historical position as an institution central to community composition, these letters illustrate how the family – and the intimate process of building families – could become an alternate site of national imagination. These two young lovers understood their marriage as an explicitly political act of community composition, and cast themselves as characters in the drama of national imagination. In negotiating their twentieth-century marriage, Rose and Gideon became political innovators, selecting, producing, and testing the content and boundaries of the nation.
