In 1948, the National Pioneering Committee of the Baha’is of Iran deputed a university student, 21-year-old Heshmat Moayyad, to travel around Iran and its environs to encourage people to arise and pioneer – that is, to journey to another place to teach the Baha’i Faith. Between 4 Dey 1327 (December 25, 1948) and 10 Bahman 1328 (January 30, 1950) -- over a year – Moayyad, who ultimately was to become a professor of Persian literature at the University of Chicago, traveled to more than 30 cities, villages and towns in central and southern Iran, Kuwait and Bahrain, recording his experiences at every stage of his journey. Nearly seventy years later, in 2015, having retained his diary from that period, he published his recollections of those travels in a memoir entitled Yad-e Yaran (Remembrances of Friends). Using close textual analysis, this paper will describe the contents of the memoir and offer an assessment of its value as a resource both for those studying the history of the Baha’i Faith and that of 20th-century Iran. It will argue that Yad-e Yaran delivers a granular and useful portrait of life in Iranian cities, villages and towns in the mid-twentieth century (including discussion of industry and populations) as well as a vivid picture of Baha’i communities in Iran and the Gulf at a relatively early stage of development, in places ranging from Arak to Golpayegan to Bandar Lengeh. In it, Moayyad not only lists the names and occupations of many of the members of far-flung Baha’i communities, but also describes how these communities functioned – how often and on what occasions they met, how they practiced their faith, and their relations with Muslim neighbors. My paper will argue that even at this relatively early stage, Iranian Baha’is had developed a sense of community and practices that were quite distinct from those of the Muslim majority.
