the Belarusian population, the usage of Polish was limited to official relations, while at home, the local language was still spoken. As a result, the Lithuanian language retreated under the pressure of Polish faster than Belarusian. This led to the formation of a compact Polish language area between the Lithuanian and Belarusian language areas, with Vilnius as the center. After some time, especially in the Vilnius region, ignorance of the Polish language was considered a lack of cultural savvy. In ceremonial situations it was advisable to use Polish. This gradually limited the use of simple speech to everyday life situations, and gave rise to a sense of contempt for it and Belarusian as the language of work, cursing, but also more emotional and impetuous.

Their representatives regarded the nobility's traditions, inextricably linked with Polishness, as a marker of prestige, so they cultivated their attachment to the Polish national tradition. And due to the lack of an impassable property and cultural barrier, they exerted influence on the surrounding peasantry. Paradoxically, this was fostered by the anti-Polish and anti-szlachta Russian policy, which gave relief to peasants for the purchase of land. As a result, the property gap between the petty gentry and the peasantry decreased, which resulted in the appearance of mixed marriages, which in turn led to the spread of Polish culture among the peasants. The emergence of the Lithuanian national movement in the 1880s slowed down the process of Polonization of the ethnically Lithuanian population, but also cemented a sense of national identity among a significant portion of the Polish-speaking Lithuanian population. The feeling of a two-tier Lithuanian-Polish national identity,
