The diaries, letters and essays are extraordinary and factual eyewitness accounts of Tabriz and Tehran’s social, military and political life in the tumultuous days and years of Iran’s Constitutional Revolution and Tabriz’s ten-month siege. She recounts the murder of Tabriz’s favorite son, Sayyid Hasan Sharifzadeh and the martyrdom of the Presbyterian’s young teacher, Howard Baskerville. She brings to life the intercommunal social and political conflicts within the western Armenian quarter of Tabriz and the successes and failures of Iran’s march to modernity under British, Russian and American occupations in the first six decades of the 20th Century. Born in Persia in the village of Haft Devan outside of the small West Azerbayjani town of Salmas on the banks of Lake Urmiah (Lake Rezayeh), she and her family moved soon after to Tabriz. From 1908 to 1909, the city remained besieged by the Shah’s troops about which she records all that a teenager might observe of the ongoing social, military, and political events and persons during and after the ten-month-siege and the occupation of Tabriz by the troops of the Russian White Army. Sarah, proficient in Azeri Turkish, Persian and Armenian as well as several European languages, continued her astute observations during the entire Reza Pahlavi rule in Tehran from 1919 to 1940 when the American evangelical and educational missions were sent home suddenly by the Reza Shah government. Following the World War, she returned to Tehran during the nationalization of Iran’s oil fields and refineries in Abadan to continue her social work and teaching in Tehran from 1954 to 1964 when she returned again to Wooster, Ohio.
