Ivan Sokolov’s work, first published in 1904, begins with a balanced overview of the situation of the Orthodox Church under Ottoman rule from the fall of Constantinople (1453) to the beginning of the nineteenth century. The author then gives a detailed description of the external situation of the Patriarchate of Constantinople from 1789 to 1900. This is followed by a discussion of the career and activity of each patriarch during this period, their relations with the bishops, their initiatives in the field of education, their regulations concerning marriage, and their work with parishes and monasteries. The book concludes with a thorough analysis of the administration of the Patriarchate during these years. Although written over a hundred years ago, this classic work has not been superseded. It is based on original sources, particularly on the patriarchal archives, to which few scholars have had access. No other existing study deals with the nineteenth-century Ecumenical Patriarchate in such a systematic and specific way. It constitutes an invaluable tool of reference. Translated from the Russian.
