There exists a small but active community for secular activism in Austria. Various initiatives, associations and individual actors are engaged intensively in the establishment of a strict separation of state and religion. They criticise the privileged position of religious communities - especially of the Roman Catholic Church - on a societal, political and legal level and one of their objectives is to make the discrimination of religiously unaffiliated people more visible. Substantive arguments in their critique are the neutrality of the state concerning worldview and religion, human rights and the ever-growing share of unaffiliated people within the Austrian population. My Master's thesis in religious studies focuses on these secular groups and organisations and their commitment to secularism. In my lecture, I will present my results based on my extensive empirical fieldwork, with a focal point on the societal, political and legal changes targeted by secular activism in Austria.
