Changes

During the reign of the emperor Justinian I (527-565), who came from the village of Tauresium in the Skopje region, a new town was built near the emperor's birthplace, named Justiniana Prima after him. The Metropolitan of Skopje was appointed an autocephalous Archbishop. Cathellian was the first Archbishop of the Archdiocese Justiniana Prima. The other archbishops were: Benenat, Paul, John I, Leon and the last one John IX, who in 680-81 took part at the Trullo Council in Constantinople.

The Slav colonisation of Macedonia began in the 7th century, when the Slavs were assimilated with the native inhabitants. Their Christianization began in the 9th century with the life and work of the holy brothers, Saints Methodius and Cyril, who came from Thessalonica. They created the Cyrillic alphabet and translated the Holy Bible from the Greek as well as several other scriptures so that the church services could be held in the vernacular. Their mission was continued by Saints Clement and Nahum of Ohrid at the end of 9th and in the beginning of the 10th century. Saint Clement founded the first University of the Slavs in this region, and Saint Nahum founded the first Slavic monastery on the shore of Lake Ohrid. In the second half of the 10th century, within the borders of Samuel's state, the autocephalous Ohrid Archdiocese was established with the rank of patriarchate. After the fall of Samuel's state, the Ohrid Archdiocese was reduced to a lower rank of church hierarchy (archbishopric) and it existed as such for eight centuries, until its abolishment in 1767 by the Turkish sultan Mustapha III, and its dioceses were annexed to the Patriarchate of Constantinople. From this moment on the Macedonian people made all possible efforts to restore the Archdiocese. Its dioceses were under several jurisdictions of the neighbouring Orthodox Churches and this struggle became particularly fierce in the second part of the 19th and the first part of the 20th century. Convenient conditions for restoration of the independence were created not earlier than during World War II (1941-1945).
