Solidarity is a concept strongly linked to the twentieth century and its burning issues of conflicts between capital and labour in a secularised world. The pressing issues at the beginning of the twenty-first century transcend secularity and pose challenges for a post-secular, globalised world of migration and movements of human beings. Since the end of the Cold War, and especially since 9/11 in 2001, the re-emergence of (often conservative) religions and the role of religious affiliations have given rise to many reflections and motivated many research projects on issues related to conflicts, minorities and religious perspectives. This chapter reflects on the challenges, difficulties and potentials for trans-religious expressions and forms of solidarity based amongst others on earlier research. What emerges out of the transformation of social structures, state structures and belief structures that take place alongside major technological changes might be understood as a situation of paradoxical conservatism or ‘subversive traditionalism’. This is a conservatism and traditionalism that continues to demand access to the benefits of modernity and ‘modern life’, while at the same time seeking to preserve a traditional or conservative (gender) order. It also gives rise to perhaps paradoxical forms of solidarity.
