Hassan-i Sabbah
Hassan-i Sabbah continued his missionary activities, which climaxed with his taking of the famous citadel of Alamut. Over the next two years, he converted most of the surrounding villages to Ismailism. Afterward, he converted most of the staff to Ismailism, took over the fortress, and presented Alamut's king with payment for his fortress, which he had no choice but to accept. The king reluctantly abdicated his throne, and Hassan-i Sabbah turned Alamut into an outpost of Fatimid rule within Abbasid territory.
