The modern understanding of representative democracy includes not only the rule of the majority, but also the protection of the rights of minorities. One such minority is indigenous peoples, including the Sámi population that lives in four European countries, namely in the northern territories of Norway, Sweden, Finland, and Russia. In these countries, the Sámi, as a minority, find it difficult to achieve an adequate level of representation in traditional political structures that are responsible for articulating interests (parties, parliaments), therefore special mechanisms were found that allowed this indigenous people to participate in political decision-making processes more actively. The purpose of the article is to study the evolution and features of the political representation of the Sámi in Norway, Sweden, and Finland. The choice of countries is dictated by the cross-border nature of the Sámi settlement and the practice of diffusion of institutions of political representation. The methodology is based on neo-institutionalism and constructivism theories. It is concluded that after World War II, global transformations of the institutional environment took place in developed countries, and they were expressed in the rejection of the racial paradigm, the establishment of the supremacy of democracy and human rights. In the countries of Northern Europe at the end of the XX — beginning of the XXI centuries, the concept of “Arctic identity” was formed instead of identity through the construct of the “Nordic race”, which was characteristic of the first half of the XX century. At the center of it is the concept of indigeneity. From the beginning of the XX century, the Sámi that were subjected to forced assimilation in all three countries (discriminatory policies of “swedification”, “norwegianization” and “finnization”) and that were forced to fight for their rights with minimal chances of winning over the dominant discourse of racial inferiority, became beneficiaries of the changes, received special status, collective rights, and opportunities for political representation in modern conditions. However, several problems and discriminatory practices against the Sámi remain relevant and require solutions at the level of public policy.
