Emigration has been known to mankind for more than a century. We name the factors contributing to emigration, give examples from the history of emigration both abroad and Russia. We emphasize that at the present time, Russian citizens emigrate to other countries, using the right to freely leave the state, and can also have dual citizenship under Russian law, or renounce citizenship, and then get it again. We pay special attention to the settlement of the territory of North Caucasus, which began in the 8th – 7th –
6th – 5th thousand BC. We analyze the features of emigration of people from North Caucasus after the October Revolution of 1917. The specifics of the emigration of people from this region of country are emphasized. Thus, the majority of people emigrated to the Ottoman Empire, and then moved to Europe. We indicate that in fact, after the adoption of the Decrees of the Central Executive Committee, the SNK of RSFSR in 1921, “On the deprivation of the rights of citizenship of certain categories of persons who are abroad” many emigrants from Russia, including North Caucasians, have become disenfranchised. This circumstance greatly influenced the publication of the Nansen passport (it was introduced in 1922 and became widespread in 1924), according to which emigrants were granted a number of legal and social rights. In addition, it is applicable to emigrants from Russia, including from the North Caucasus, in 1922 and 1926. The Geneva definition of “Russian refugee” was given, and the International Convention on the International Status of Refugees of 1933 created an alternative to naturalization for refugees from Russia. Subsequently, before the outbreak of the Second World War, people received, as a rule, the citizenship of the countries in which they began to live.
