For the first time in Gagauz studies, this article examines the Gagauz ethnic group in Belarus, the first stage of its formation took place in the Soviet period: their perception of the concept of "homeland", their identification of the country of residence, etc. Based on the data of the survey conducted by the author, it is concluded that they are well adapted to the Belarusian sociocultural space and are aware of themselves as part of it. This is explained by the length of their residence in this country, as well as by the fact that they have created families here, “put down roots”, gave birth to children and grandchildren, and adopted Belarusian citizenship. As the frequency of contacts with their first homeland decreased, and especially after their parents passed away, their perception of Belarus as their homeland increased. In conclusion, it is noted that the identification of Belarus by the Gagauz of the second wave (who migrated in the post-Soviet period) has significant differences.
