Zachary J. Foster argued in a 2015 "Foreign Affairs" article that "based on hundreds of manuscripts, Islamic court records, books, magazines, and newspapers from the Ottoman period (1516–1918), it seems that the first Arab to use the term "Palestinian" was Farid Georges Kassab, a Beirut-based Orthodox Christian." He explained further that Kassab's 1909 book "Palestine, Hellenism, and Clericalism" noted in passing that "the Orthodox Palestinian Ottomans call themselves Arabs, and are in fact Arabs," despite describing the Arabic speakers of Palestine as Palestinians throughout the rest of the book."
