Our Lady of Guadalupe, kept on 12 December, commemorates the apparitions reported in 1531 near Mexico City, in which the Virgin is said to have appeared to the indigenous convert Juan Diego on the hill of Tepeyac, speaking in Nahuatl, and to have left her image imprinted on his cloak (the tilma), still venerated in the basilica built on the site. The shrine is among the most visited Catholic pilgrimage places in the world.
The devotion carries a weight far beyond the liturgical. The dark-skinned Virgin, appearing to an indigenous man and speaking his language on a site associated with an earlier sanctuary, became a symbol of a specifically Mexican Christianity and, later, of national identity itself; her banner was carried in the independence struggle, and she is invoked across the Americas as patroness. Historians distinguish the confessional account from the documentary record: the earliest surviving narrative, the Nahuatl Nican mopohua, and the debate over the sixteenth-century evidence and the silence of the first bishop, Zumarraga, are matters of continuing scholarly discussion, which the church's recognition of the devotion has not foreclosed.
