This paper explores how the concept of plurilingualism is positioned to act as an impetus for linguistic and cultural inclusion in human-rights-based language education. Drawing on frameworks foregrounding descriptors for plurilingualism and democratic citizenship, the paper employs discourse analysis and sorting techniques to identify and align strategies of linguistic and cultural inclusion found in multimodal plurilingual task artefacts collected from a multi-year, multi-site research partnership between a Canadian university and the Italian Ministry of Education. The findings reveal that the implementation of plurilingual tasks aligns with key elements of democratic, rights-based language education, including critical understanding of communication, openness to cultural otherness, cooperation skills, and the valuing of cultural diversity. The findings of this paper contribute to further understanding of the concept of plurilingualism and to empirically informed perspectives on pedagogies that support language rights as human rights in education.
