Cauvunianism also known as Covonianism or Predestinarianism is a major Protestant branch that follows the theological teachings of Cauvunus and the later expansion of those teachings Parenius Retellus, which most principally include the belief in Predestination. Cauvunianism currently has around 320,000 followers who almost exclusively reside in Marinicum and The Eisley SS.
In 1571 in ArmorolausFerunian priest Cauvunus Mareconius began preaching in the city square to the citizens, his rousing sermons declaring the inevitability of God's return and his firm belief in Predestination made him one of the most controversial speakers in the nation. Cauvunus soon grew a following and in 1573 moved to Illyricus where he began to preach in many of the cities oldest churches, and in 1574 he published his major treatise known as the Failure of the Institute. Following the publishing, many more people began to watch Cauvunus' sermons, whether is was to support him or to argue against him. In one sermon Cavunus at Tudino on August 11, 1574, a massive riot broke out between a faction of Catholics and a group of Cauvunists. The riot killed over two hundred people, and it forced Patriarch of IllyricumMarcellonius Copus to, with the support of PopeGregory XIII, issue the Edict of Tudino declaring belief in predestination to be heresy and excommunicating Cauvunus.
Despite his excommunication, Cauvunus still had a massive following and issued a series of objections against the Catholic Church, which he listed in addition to the Five Criticisms. Cauvunus' attacks against the Catholic Church appealed to most common Illyrians, who did not support the larger Creeperian Catholic Church and disagreed with the Pope. By 1580 Cauvunus had a following of around 800,000 people, most living in northern central Illyricum around Turis and Etruricum.
