Abstract: The article's research subject is the scientific work of the outstanding Soviet scholar, representative of the "Russian school" scholars of English history, Sergei Ivanovich Arkhangelsky (1882-1958). As the object of research, the author chose the scholar's work focused on the study of the history of England's foreign policy in the 17th century within the system of international relations. In studying this topic, the author conducted a comprehensive examination of his published works and of the materials stored in his personal funds (the Archive of the Russian Academy of Sciences, the Central Archive of the Nizhnegorskaya Oblast, the Science Museum of Nizhni Novgorod State University). The author also separately examined the scholar's popular works on various aspects of the USSR foreign policy and the history of international relations, which were not related to his scientific work. Additionally, the author considers "The History of England's Foreign Policy in the 17th Century," which was one field of scientific interest of S. I. Arkhangelsky, in the context of the Soviet stage in the development of the "Russian school" of English history. This approach includes the study of the topic's aspects from the general (the Soviet stage of the “Russian school” of English history) to the particular (the scientific work of S. I. Arkhangelsky). The leading research method for this study of the scientific work of S. I. Arkhangelsky is the biographical method. The novelty of this research lies in the author's proof of a previously unknown fact from the scientific biography of S. I. Arkhangelsky: from the late 1930s to the middle of the 1950s., he worked on a monograph on the history of England's foreign policy in the 17th century. Consequently, the scholar's scientific work on the history of England’s foreign policy should be viewed as part of a monograph he had envisioned.

Abstract: The research subject of this article is the ideological, theoretical and methodological views of S. I. Arkhangelsky, Doctor of Historical Sciences, Professor, Corresponding Member of the USSR Academy of Sciences, during the early period of his scientific work (the beginning of the 20th century to the middle of the 1920s.). In order to obtain objective results from the research, the author founded the study on the materials from the scholar's personal archival funds (the Archive of the Russian Academy of Sciences, the Central Archive of the Nizhnegorskaya Oblast, the Conservation Center of Documents up to 1917 and the Science Museum of Nizhni Novgorod State University). The author identified the main topics that interested the scholar in the early period of his work, including the genesis of capitalism and social history. The article's leading research method is the biographical method. The indicated research topic is considered through the prism of the scientific biography of S. I. Arkhangelsky. For the first time in historiography, Arkhangelsky's plan for a monograph on the history of the development of capitalism is introduced into scientific circulation. The author establishes that the origin of the scholar’s interest in social history should be associated with his professional formation under the conditions of the general transition from the study of the state to the study of social history, which began in the middle of the 19th century. These trends joined the aims and objectives of local history studies in the 1920s. The author attests S. I. Arkhangelsky's understanding of the continuity and unity of development between academic science and historical local history. From the general trends of recreating the social history of mankind, which received a new impetus for development under the influence of the revolutionary transformations at the beginning of the 20th century, S. I. Arkhangelsky began to study the social history of the Nizhny Novgorod region (the history of the peasantry, the history of the industrial proletariat) and the social history of England.
