This study examines the systematic erasure of language and identity in the occupied territories of Ukraine as a tool of colonial domination. Using qualitative content analysis, the research draws on official reports, media sources, and testimonies documenting Russian policies targeting the Ukrainian linguistic and cultural landscape. The data include cases of forced Russification in education, media, and public spaces, the destruction of Ukrainian books and libraries, and the removal of Ukrainian-language signage and memorials. The findings reveal a systematic effort to eradicate Ukrainian identity through linguistic suppression, aligning with historical patterns of imperial domination. Cultural erasure is further reinforced through the promotion of Russian historical narratives and the suppression of Ukrainian heritage. This research situates these practices within the broader framework of coloniality and linguicide, highlighting the role of language as both a site of resistance and a target of oppression.
