On the same trip, the Pope crossed another, more pointedly symbolic boundary. His journey retraced the mythic pilgrimage of his namesake, St. Francis, who travelled to Egypt, in 1219, in a futile attempt to end the Crusades. The saint may have imagined converting the local sultan, but what he mostly sought was a détente between Islam and Christianity. That religious divide persists today, of course, and still carries a Crusader legacy. In Cairo, Pope Francis met with Muslim leaders at Al-Azhar University, which was established more than a hundred years before Oxford and remains the most important religious educational institution in the Muslim world.
