Drawing upon French philosophy, this study offers a novel empirical and conceptual understanding of the newly launched European Universities Initiative. In 2019, higher education institutions across the European Union created 17 new alliances as part of the first pilot phase of the initiative. This is an experiment in European and global higher education. This paper offers a conceptual contribution to the field of higher education studies, making use of a rhizomatic analysis to explore how university alliances build what the European Commission refers to as the 'European universities of the future.' Based on the conceptual reflection and findings from a small-scale empirical study, this paper concludes that the alliances within the European Universities Initiative rely on pre-existing higher education and research partnerships while at the same time experimenting to foster a diversity of institutional forms to achieve the ambitious goal of creating 'European Universities.'
