Gregory of Nin

Gregory of Nin was a Croatian Catholic prelate who served as a medieval Bishop of Nin and strongly opposed the pope and official circles of the Catholic Church. He introduced the Croatian language in the religious services after the Great Assembly in 926, according to traditional Croatian historiography. Until that time, services were held only in Latin, not being understandable to a majority of the population. Not only was this important for Croatian language and culture, but it also made Christianity stronger within the Croatian kingdom.
