The dynamics of the legal content of the principles of Russian citizenship and the impact of the 2020 constitutional amendments on It

The purpose of the article is to analyze the legal content of the basic constitutional principles of citizenship — single and equal citizenship, as well as the principle of prohibition of deprivation of citizenship. The analysis of the basic principles of citizenship is carried out taking into account the constitutional amendments of 2020. The article shows the evolution of the legal content of the principles of citizenship from the Soviet period to the present. The author comes to the conclusion that, while remaining unchanged textually, the content of these principles has undergone a significant transformation in the legislation on citizenship specifying the constitution. It is concluded that the principle of prohibition of deprivation of citizenship has undergone the greatest transformations and, according to the author, exists today only nominally. The political and social context of all the changes affecting the content of the constitutional principles of citizenship is confirmed. At the same time, such changes are assessed in a positive aspect as contributing to ensuring the security of the state and society.
