|City in northwestern Iran in which the fiercest and most devastating of the three military campaigns against the Bábís took place in May 1850. When Ḥujjat returned to Zanján after his detention in Ṭihrán, he was the object of hostility on the part of the authorities. The city was split into two opposing camps, and Ḥujjat and his companions were forced to seek safety in the nearby fort of 'Alí-Mardán K̲h̲án, about three thousand in all. They held the fort against repeated attack and siege for nearly nine months. Ḥujjat was wounded, his wife and baby killed, and then he himself died. In the fierce attack the remaining Bábís were struck down. The survivors were tortured, killed and their bodies mutilated.
