Major Occultation of Muhammad al-Mahdi begins
The Major Occultation, according to Shia, is Hujjat-Allah al-Mahdi's second occultation after the Minor Occultation. According to Twelvers, the Major Occultation which came around the year 329AH/941CE is still in effect, and will not end until the end of time when the Mahdi returns to reestablish justice on earth.
