In the nineteenth-century Sokoto Caliphate, Nana Asma'u, a scholar fluent in multiple languages and daughter of the jihad's leader, trained itinerant women teachers called jajis who carried her instructional poems into rural areas and taught them to secluded women. The poems were composed to be memorized and recited, functioning as portable curricula that reached students the teacher could never meet in person.
Asma'u composed verse not primarily as literary expression but as a durable delivery device: mnemonic structure, recitation, and formulaic patterning let a single lesson travel through intermediaries and survive without the author present. The medium was chosen for transmissibility across distance and illiteracy, not for aesthetic display.
Rather than teaching students directly, the model credentials and dispatches intermediaries (jajis) who are themselves taught the material and sent to teach others, extending one educator's reach beyond her physical and social constraints. Reach scales by investing in teachers of teachers, with standardized recitable content holding the chain together.
The book argues that within a system of female seclusion, women's education expanded by bringing instruction to women rather than bringing women to instruction, using female teachers who could enter domestic spaces. Social restriction on movement was worked around by redesigning who travels, showing the constraint limited mobility but not literacy.
