The largest of the later confraternities is the "Archconfraternity for the Relief of the Poor Souls in Purgatory under the title of the Assumption of Mary" (founded 1841) in the Redemptorist church of Santa Maria in Monterone at Rome. It expanded rapidly to England and North America, and was endowed with indulgences in 1841-63. Priests empowered to receive the faithful into the confraternity enjoy various other faculties. This confraternity is especially adapted for rapid expansion, because in 1860 it was authorized to aggregate every confraternity of whatever name and object and to communicate to them its graces and privileges, provided they added to their original titles "and for the relief of the Poor Souls in Purgatory"; they must not, however, be already aggregated to another archconfraternity, nor have been endowed with indulgences on their own account. The Redemptorist Fathers still conduct this archconfraternity which is now known as the "Purgatorian Archconfraternity".
