The modern city of Meissen owes its origin to a castle built by King Henry I the Fowler about 928 to protect German colonists among the pagan Wends.
Pope John XII consented, and shortly before the execution of the plan in 968 it was decided at the Synod of Ravenna (967) to create three bishoprics — Meissen, Merseburg, and Zeitz — as suffragans of the Archbishopric of Magdeburg.
Escaping, he joined the Saxon princes, espoused the cause of Pope Gregory VII, and in 1085 took part in the Gregorian Synod of Quedlinburg, for which he was deprived of his office by the emperor, a more imperially disposed bishop being appointed in his place.
Among the later bishops, who ranked after the 13th century as prince-bishops (Fürsten) of the Holy Roman Empire, however, again and again disputed in that position by the Margraves of Meissen, the most notable are Wittigo I (1266–1293) and John I of Eisenberg (1340–1371).
John VI of Salhausen (1488–1518) further impoverished the diocese through his obstinate attempt to obtain full princely sovereignty in the temporal territories ruled by his see, which brought him into constant conflict with George, Duke of Saxony; his spiritual administration was also open to censure.
John VII of Schleinitz (1518–1537) was a resolute opponent of Martin Luther, whose revolt began in neighbouring Wittenberg, and, conjointly with George of Saxony, endeavored to crush the innovations.
John VIII of Maltitz (1537–1549) and Nicholas II of Carlowitz (1549–1555) were unable to withstand the ever-spreading Protestant Reformation, which after the death of Duke George (1539) triumphed in Saxony and gained ground even among the canons of the cathedral, so that the diocese was on the verge of dissolution.
The last bishop, John of Haugwitz (1555–1581), placed his resignation in the hands of the cathedral chapter, in virtue of an agreement with Elector Augustus of Saxony, went over to Lutheranism, married and retired to the castle of Ruhetal near Mögeln.
Before his resignation and conversion Haugwitz appointed Johannes Leisentritt as diocesan administrator, seated in Bautzen, competent for the Lusatian areas of the diocese outside of Saxony.
However, in 1567 the Holy See separated the Lusatian areas from the Saxon parts of the diocese and established there the Apostolic Prefecture of Meißen, seated at St. Peter's in Bautzen, with Leisentritt as its first prefect.
When in 1635 the Lutheran Electorate of Saxony annexed the Two Lusatias it guaranteed in the cession contract (Traditionsrezess) with Bohemia to leave the existing religious relations untouched.
[3] In the years between 1945 and 1948 the number of parishioners in the Meißen diocese more than doubled because many Catholic refugees and expellees from former Eastern Germany and Czechoslovakia found refuge within its diocesan area.
On 24 January 1948 Bishop Petrus Legge conveyanced his jurisdiction for that Polish-annexed diocesan area to Karol Milik, the apostolic administrator of that part of the Breslau archdiocese outside of the Soviet Occupation Zone in Germany, which had also been annexed to Poland.
