This article examines the situation of a not well-known local sufi Order of Ottoman Aleppo, the Zayniyyah, around the end of the 17th century, through the use of a legal document preserved in the Ottoman Court Records of the city. By recording a dispute over the leadership of the order, the document constitutes precious evidence on the history of the Zayniyyah, the importance of organized Sufi brotherhoods in Ottoman Aleppo and the keen interest shown by the Ottoman power system in monitoring the activities and dealings of Sufi orders.
