Raised in Cairo in the 1940's, by a generation of women who never wore the veil or headscarf, Leila Ahmed set out to discover why so many women now wear the veil, and what this shift means for women, Islam and the West.
At a time when both Islamist and democratic forces are dramatically changing the Middle East, Leila Ahmed's analysis of the resurgence of the veil from Egypt to Saudi Arabia challenges many assumptions about women's rights and activism.
Leila Ahmed was the first professor of Women's Studies in Religion at Harvard University and is author of Women and Gender in Islam.
