This paper examines issues related to the important impact of language policy in the Basque Country in recent decades. Basque, a minority language that was not allowed in the public space until the late 1970s, is an official language along with Spanish in the Basque Autonomous Community. The development of Basque has been most significant in education where it is not only a school subject but also the main language of instruction for most children. The paper briefly summarises this development and then moves to a focus on the use of Basque at the university level. The legal and organisational bases supporting the use of Basque are explained as well as the challenges faced by a minority language in higher education. The paper discusses the tension between internationalisation and the use of Basque for teaching and research in higher education. (Contains 2 tables and 5 figures.)
