The Buffalo Agency came to an anticlimactic end at the close of the 1960s when the building itself was demolished to make way for new construction in the Tulun district.1 Although the Ibn Tulun Mosque itself remains standing, much of the neighborhood surrounding it has been rebuilt. The area where the Agency once stood is today a collection of homes, mobile-phone shops, and grocery stores that make up every other part of the modern city of Cairo. A visitor to the area today would never know that a vibrant community of Maghribi Ibadis had operated a trade agency, school, and library in that neighborhood for over three centuries.
