The Republic of Kosovo’s self-declared multiethnic society has strived to construct an inclusive attitude and tolerating spirit toward all communities within. This study has explored how group-differentiated rights are used to construct identity and multiethnicity in relation to European integration in four official documents using the research questions; how is the production of identity and multiethnicity through group-differentiated rights in Kosovo constructed in the documents and related to EU integration; and how has the EU accession process affected the construction of multiethnicity and identity in Kosovo’s documents on minorities relating to group-differentiated rights? An ethnographic content analysis and comparative design, with a social constructivist perspective, grasping the constituents of group-differentiated rights concerning exclusive rights granted to minorities employed to develop, and safeguard identities was applied. The key findings have demonstrated that the development of group-differentiated rights through multiethnicity and identity relating to EU accession and integration may be considered mutually constitutive, creating a path for Kosovo's future EU membership and a sustainable multiethnic society founded on democracy and the rule of law. Although, Kosovo has demonstrated a readiness to adjust and adhere to EU directives, adequate implementation of minority and human rights is the first and primary step toward EU membership.
