In 1946 a short autobiographical account of Ḥaydar Khān ᶜAmū Ughlū, the Caucasian revolutionary who participated in the Iranian Constitutional movement, 1905-1909, appeared in the Persian monthly journal, Yādigār. The article, which was accompanied by an introduction as well as by some concluding remarks, was unsigned. The editorial policies of the journal, however, indicate that unsigned articles were written by ᶜAbbās Iqbāl, the editor. Iqbāl does not attempt to establish the authenticity of this account, nor do other historians who have used it in their research. While in the absence of the document its authenticity cannot be established, it is possible to make some comments concerning the probability that this may be authentic and that the events mentioned in the autobiography took place, the role Ḥaydar Khān played in these events, and the significance of these events for the Iranian political structure.
