Ohrid is the reason this territory matters in religious history out of all proportion to its size. Clement and Naum, disciples of Cyril and Methodius, settled here in the late ninth century and ran what is usually described as the first Slavonic university: a school that trained clergy in the Slavonic liturgy, refined the script and sent literate priests out across the Slavic world. The lake, the town and its churches are inscribed by UNESCO for both natural and cultural value, one of a small number of mixed sites anywhere.
The modern religious map is about two thirds Orthodox and about a third Muslim, and the division follows ethnicity rather than crossing it: the Muslim population is almost entirely ethnic Albanian and Turkish. That alignment is what made the conflict of 2001 possible and what the Ohrid Framework Agreement that ended it was designed to manage, through language rights, decentralisation and proportional representation rather than through anything explicitly religious.
Sufi orders remain active here in a way they do not in most of Europe. The Arabati Baba tekke at Tetovo, a Bektashi foundation of the eighteenth century, is the best known, and it has been the subject of a long dispute over ownership and use between the Bektashi community and the official Islamic Religious Community of North Macedonia.
Registration of religious bodies has been contentious. The state's refusal to register a small Orthodox body under the Serbian Patriarchate produced a European Court of Human Rights judgment against North Macedonia, and its leader was imprisoned, a case widely criticised at the time.
