In terms of women's rights, the Aga Khan was more progressive in his views than Sir Sayyid and many other Islamic modernists of his time. The Aga Khan framed his pursuit of women's rights not simply in the context of women being better mothers or wives, but rather, for women's own benefit. He endorsed the spiritual equality of men and women in Islam, and he also called for full political equality. This included the right to vote and the right to an education. In regards to the latter issue, he endorsed compulsory primary education for girls. He also encouraged women to pursue higher university-level education, and saw nothing wrong with co-educational institutions. Whereas Sir Sayyid prioritized the education of boys over girls, the Aga Khan instructed his followers that if they had a son and daughter, and if they could only afford to send one of them to school, they should send the daughter over the boy.
