Marian apparitions and devotions since the early 19th century have been unique enough to consider them on their own terms. In what devotees have dubbed the "Marian Age," apparitions tend toward conservative politics and messages; a context of struggle; ambiguous attitudes toward modernity, globalization, and technology; and apocalyptic worldviews. Many of these modern apparitions are interconnected, becoming validated through their overlaps, continuities, and congruencies alongside-and often outside-traditional channels of Roman Catholic Church leadership. Apparitions and the devotional cultures associated with them raise for scholars important questions, including the problem of how they should be categorized and studied.
