Vernacular Legalism in the Ottoman Empire: Confession, Law, and Popular Politics in the Debate over the “Religion of Abraham (millet-i Ibrāhīm)”

In the seventeenth century, Ottoman jurists repeatedly tried to stop Muslims from stating that they “belonged to the religion of Abraham.” A century earlier, however, the expression had been a core part of the new confessional identity of the empire’s Muslims. This article explores how the phrase changed from an attestation of faith to a sign of heresy through a study of a short pamphlet by Minḳārīzāde Yaḥyā Efendi. Minḳārīzāde argued that the use of the phrase is not permissible and addressed his arguments not to learned scholars, but to the semi-educated. I argue that Minḳārīzāde’s pamphlet provides a glimpse into “vernacular legalism” in action in the Ottoman Empire, that is, how semi-educated audiences received and understood legal debates and subsequently turned law into a space of popular politics.
