Nana Asma'u (full name: Nana Asma’u bint Shehu Usman dan Fodiyo, Arabic: نانا أسماء بنت عثمان فودي‎; 1793–1864) was a princess, poet, teacher, and daughter of the founder of the Sokoto Caliphate, Usman dan Fodio. She remains a revered figure in northern Nigeria. Nana Asma'u is held up by some as an example of education and independence of women possible under Islam, and by others as a precursor to modern feminism in Africa.
