Recently reedited in a facsimile version by the Editions of the University of Tehran, the weekly Habl al-matin [“Strong Cord”], one of the most influential Iranian Constitutional and anti-Russian, then pro-Reza Shah newspapers, edited in Calcutta with interruptions from 1893 to 1930, is studied through the five distinctive periods of its history.  The Habl al-matin’s influence outside Iran—especially in Bukhara where its impact is well documented by a number of early twentieth-century Persian-language sources—is unfortunately not assessed.  The paper ends with a paragraph on the two homonymous daily newspapers published in Tehran and in Rasht in the early twentieth century.
