Nogai muhajirism to the Ottoman empire during the Caucasian war

This article is devoted to tragic circumstances of the major Nogai migration to the Ottoman Empire in the end of the Caucasian war. The first part says about the term “hijra”, its meaning, conditions and other characteristics according to the Quran. Then it comes to the historic context of this event, the political position of Nogai in this period. Particular attention is paid to the economic, political and religious causes of the nomads’ relocation which are not dictated by just the result of the war given their minor participation in the military operations. The author made an attempt to consider theological justification of the terms “hijra” and “muhajirism” as well as their appropriate usage in Russian historical science.
