How a Secret Mission in Syria Built the Fatimid Empire | Ismaili History, Part 1

Eleven hundred years ago, a family hiding in a small Syrian town ran one of history's most effective secret networks — and launched an empire that built Cairo and al-Azhar. This is the untold history of the Ismailis of Syria: from the hidden imams of Salamiyah to the Fatimid Caliphate, the mountain castles of Masyaf, the "Assassin" myths, Ottoman treason trials, and survival through war to today.
