By presenting her work in the Galician language, she played a pivotal role in its revival and encouraged other writers to explore and document their heritage. The publication of 'Cantares Gallegos' marked the beginning of a literary movement that advocated for the significance of regional languages and identities, embedding a sense of pride and cultural awareness amongst Galicians. This was instrumental in shaping the Galician language's literary landscape and laid groundwork for future movements aimed at linguistic and cultural preservation.
