ENThe brotherhoods (Confraternities) on the Ukrainian and Belarusian lands were civil associations of the citizens, thus not church organisations but secular ones. These played great role in the shaping and developing of the national awakening and national identity of various Slavic peoples in the Habsburg Empire. There are various church collections of books in the contemporary Hungary, those contains about or more than one thousand old printings in Cyrillic letters. The 80% of these books are of Ukrainian origin. These liturgical books of Ukrainian origin were transmitters of influences of the European (and mainly Polish baroque). The books came to the Orthodox Serbs and the Greek-Catholic (Uniate) Carpathian Rusyn-Ukrainians by the import of these books.
