What does it mean for a new religion to arise or take hold among a group of people? What does it mean for a religious tradition to endure? These are questions that are quite commonly addressed, at least implicitly, in the study of religion. Less frequently asked is the question of what it means for a religious tradition to come to an end. This article addresses this question, paying particular attention to the ways people actively dismantle a religious tradition that previously shaped their lives. I also consider what studying the process of religious disappearance can teach us about what it means for a tradition to arise and endure, arguing that a grasp on processes of religious dissolution is necessary for a fully rounded approach to the study of religious change. Throughout the article, I illustrate my arguments with material from the study of Christianity, Judaism and indigenous religious traditions, particularly from Oceania.
