What is the future of ‘citizenship’ and solidarity in times of global migration, rising uncertainty, and increasing inequality worldwide? In 2020, the UNHCR took a landmark decision ruling that host countries cannot force ‘climate refugees’ home. However, studies on critical citizenship show that access to refugee status, permanent residency or citizenship in Denmark and other EU countries have become restricted to socially privileged individuals. In 2016, the population of non-EU migrants in the European Union grew up to 22 million, with EU member states granting citizenship to less than one million persons. At the same time, In regions affected by rising sea levels and in the Pacific, poor people affected dramatically by rising sea levels are rescuing and hosting refugees; and in the Global North migrants use protest, strike, blockades, or hunger strikes and marches to make public claims for their rights. Migrants’ access to public voice and solidarity by majority citizens is limited through explicit and implicit boundaries of race/ethnicity, language, and ‘deservingness’ standards. Under what conditions does protest, public voice, and self-organized communities of solidarity create new forms of citizenship beyond these boundaries? Connecting empirical case studies with theory, this course is going to focus on migrants’ public protest and people’s solidarity actions through the perspectives of ‘acts of citizenship’ (Isin) and ‘political translation’ (Doerr). The course tries to answer single themes from an interdisciplinary perspective based on empirical, comparative case studies on different regions and based on non-western, feminist, and postcolonial and historical perspectives.
