Sedevacantism is a traditionalist Catholic movement which holds that since the death of Pius XII the alleged occupiers of the Holy See are not valid popes due to their espousal of one or more heresies and that, for lack of a valid pope, the See of Rome is thus vacant. Sedevacantism owes its origins to the rejection of the theological and disciplinary changes implemented following the Second Vatican Council (1962–1965).

false, captious, ill-sounding, offensive to pious ears, scandalous, pernicious, rash, injurious to the Church and its practices, contumelious to Church and State, seditious, impious, blasphemous, suspected and savouring of heresy, favouring heretics, heresy, and schism, erroneous, bordering on heresy, often condemned, heretical, and reviving various heresies, especially those contained in the famous propositions of Jansenius.

Mariological papal documents have been a major force that has shaped Roman Catholic Mariology over the centuries. Mariology is developed by theologians on the basis not only of Scripture and Tradition but also of the sensus fidei of the faithful as a whole, "from the bishops to the last of the faithful", and papal documents have recorded those developments, defining Marian dogmas, spreading doctrines and encouraging devotions within the Catholic Church.
In 1800 the Catholics were a small minority everywhere except Maryland. Immigration from Ireland and Germany gave them millions of adherents from the 1840s to the 1880s. Then came millions more from Italy, Poland and Eastern Europe, as well as French Canada. Large numbers of priests and nuns came from Ireland and France. The Irish soon dominated the clergy church, with a great majority of bishops by 1900. As the immigrants arrived new parishes and diocese were created. Rebuffed in efforts to obtain government funds for schools, the Catholics set up a parochial school system largely staffed with nuns. It reached about a third of the children. They also set up colleges. There were few Catholics in the South, apart from Louisiana. However they were well represented in the nation's cities, mill towns and mining centers. Anti-Catholic politics flared briefly in the 1850s, but the Catholic voters surged into the Democratic Party and Irish Catholic politicians played increasingly dominant roles in Democratic machines in Boston, New York, and other major cities. Devotional practices included daily rosary prayers, regular attendance at Sunday Mass, and special roles for devotion to the Blessed Virgin Mary and favorite saints.
