Matica srpska
Strossmayer aided the creation of the printing house in Cetinje, helped found the "Matica slovenska" and actively supported "Matica srpska", the national culture societies of the Slovenes and the Serbs, respectively. In 1861, he had the book "Bulgarian Folk Songs" by the Miladinov Brothers from Macedonia printed in Zagreb. He also had several Glagolitic missals printed in the spirit of restoring the Slavonic liturgy that connected the two Christian religions of the South Slavs, and revering the work of saints Cyril and Methodius.
