Universalis Ecclesiae is the incipit of the papal bull of 29 September 1850 by which Pope Pius IX recreated the Roman Catholic diocesan hierarchy in England, which had been extinguished with the death of the last Marian bishop in the reign of Elizabeth I. New names were given to the dioceses, as the old ones were in use by the Church of England. The bull aroused considerable anti-Catholic feeling among English Protestants.
When Catholics in England were deprived of the normal episcopal hierarchy, their general pastoral care was entrusted at first to a priest with the title of archpriest (in effect an apostolic prefect), and then, from 1623 to 1688, to one or more apostolic vicars, bishops of titular sees governing not in their own name, as diocesan bishops do, but provisionally in the name of the Pope. At first there was a single vicar for the whole kingdom, later their number was increased to four, assigned respectively to the London District, the Midland District, the Northern District, and the Western District. The number of vicariates was doubled in 1840, becoming eight, the apostolic vicariates of the London district, the Western, the Eastern, the Central, and the districts of Wales, Lancashire, Yorkshire, and the North.
The legal situation of Catholics in England and Wales was altered for the better by the Catholic Relief Act 1829, and English Catholics, who before had been reduced to a few tens of thousands, received in the 19th century thousands of converts from Anglicanism and millions of Irish Catholic immigrants, so that Catholics came to form some 10% of the general population of England and a considerably higher proportion of church-goers.
