Abstract: This article conduct an analysis of ethnocultural stereotypes of the Steppe Crimean Tatars and Dobruja (Romanian) Tatars based on proverbs of the turn of XIX and XX centuries. The subject of this research became the Kipchak Crimean Tatar paremiological fund of that period. The goal consists in an accurate, tolerant elucidation of the topic. Initially, the stereotypes are divided into auto-stereotypes, which is an outlook upon the own ethnic group; and hetero-stereotypes, which is the representations on a neighboring ethnos. The first ones, being an inseparable part of national identity, are prone to exaggeration of merits of their ethnos and carry a complementary character. This fact impedes a realistic assessment of the merits of neighboring ethnos, which is compared to the own in accordance with cultural values. The determined differences serve as a foundation for hetero-stereotypes, which usually belittle the positive sides of the other national portrait. The scientific novelty consists in examination of ethnocultural stereotypes based on proverbs of the turn of XIX and XX centuries. Which contributed to fuller understanding of the mentality of Crimean Tatars and Dobruja (Romanian) Tatars being a diaspora of Crimean Tatar ethnos. Paremiological material allowed dividing the stereotypes into auto-stereotypes and hetero-stereotypes. The research results offered an opportunity to determine and explore the ethnic composition of Crimean Peninsula of the turn of XIX and XX centuries.
