On Wednesday evening, 17 October 1850, at the height of ʿId al-adha, the Muslim Feast of Sacrifice, riots broke out in Aleppo in northern Syria, starting with Muslim riots in the Christian quarters of Judayda and Saliba. For two days, Muslim rioters looted homes and churches in these and other Christian quarters in the city, killing and wounding a number of the inhabitants. Only on Friday did the riots cease, but the insurgents then presented a list of demands to the authorities as a pre-condition for the restoration of order to the city. Their principal demands were that the authorities‧ intention to impose military conscription on Muslims be revoked, that the ringing of church bells and the carrying of crosses in public religious processions be banned; and that the owning of Muslim slaves by Christians be prohibited. The Ottoman governor, Mustafa Zarif Pasha, at first consented to the demands of the rioters, and even took certain steps to restore calm to the ruffled atmosphere, such as declaring that the firda head tax, one of the inflammatory factors that had contributed to the riots, would be transformed into a property tax.
