McMurray’s chapter argues that law is a profoundly sonic medium, acting in, through, against, and modeled on sound—and more particularly, voice. Legal and cultural reforms in Islamicate societies in the Black Sea region during and around the time of the Crimean War illustrate these dynamics especially well. The first part of the chapter compares the legal reforms of the Caucasian Imamate (in North Daghestan and Chechnya) and the Ottoman Empire, showing how sound played a central role in negotiating new meanings of Islamic shari‘a law within those societies. Law thus becomes a critical archive for histories of sound, vocality, and listening. The latter part then reflects on the ontologies of law as a medium, considering both its sonic qualities—a recurring motif in both Anglo-American and Islamic jurisprudence—and its relation to the telegraph in particular, as a communications technology that simultaneously facilitated and challenged extant legal regimes.
