The motivation for this project was based on the newly founded movement DiEM25 (Democracy in Europe Movement 2025) and their manifesto. The movement’s ideas and visions are based on the critique of the European Union’s handling of the economic, refugee and migration crisis’, that has been debated throughout Europe in recent years. With their manifesto, DiEM25 has formulated an idealistic alternative vision for the future Europe. This assignment seeks to find answers to what kind of alternative this is. More specifically; which kind of cosmopolitanism is expressed in the manifesto, and which European concept historical traditions this cosmopolitanism builds upon. The analysis conducted in this project will be a comparative concept historian analysis of the cosmopolitan vision formulated in the DiEM25 Manifesto. The assignment concludes that the manifesto entails a potential utopian cosmopolitan vision of re-democratising Europe, and more specifically the EU in our present modern and globalised world. Furthermore, it concludes that the the cosmopolitanism in the DiEM25 Manifesto builds on a long tradition of cosmopolitan ideas, leading back to Immanuel Kant initial ideas of cosmopolitanism, through post world war and the thoughts of Ulrich Beck up until the 21st century and the notion of New Cosmopolitanism.
