Sirmium, situated near the modern town of Mitrovitz in Slavonia; its church is said to have been founded by St. Peter. The district of Szerém was subject to the Archbishop of Kalocsa after the Christianization of Hungary. In 1228, the archbishop petitioned the Holy See, in consideration of the large extent of his diocese, to found a new bishopric, and in 1229 Gregory IX established the See of Szerém, the jurisdiction of which covered almost exclusively the country on the right bank of the Sava River. The see was under the Turkish Government in 1526. It had no bishop from 1537 to 1578, and was held by a titular bishop after 1624. In 1709 the see was re-established with some changes in its territory. Clement XIV united it with Bosnia and Diakovár in 1773.

The Catholic Encyclopedia is the most comprehensive resource on Catholic teaching, history, and information ever gathered in all of human history. This easy-to-search online version was originally printed between 1907 and 1912 in fifteen hard copy volumes.

Catholic Encyclopedia

Designed to present its readers with the full body of Catholic teaching, the Encyclopedia contains not only precise statements of what the Church has defined, but also an impartial record of different views of acknowledged authority on all disputed questions, national, political or factional. In the determination of the truth the most recent and acknowledged scientific methods are employed, and the results of the latest research in theology, philosophy, history, apologetics, archaeology, and other sciences are given careful consideration.

No one who is interested in human history, past and present, can ignore the Catholic Church, either as an institution which has been the central figure in the civilized world for nearly two thousand years, decisively affecting its destinies, religious, literary, scientific, social and political, or as an existing power whose influence and activity extend to every part of the globe. In the past century the Church has grown both extensively and intensively among English-speaking peoples. Their living interests demand that they should have the means of informing themselves about this vast institution, which, whether they are Catholics or not, affects their fortunes and their destiny.
