[5] Being under strong pressure from Croatian Catholic clergy and state officials to recognize Papal jurisdiction, and to convert the population of his bishopric to Eastern Catholicism (Uniate), Simeon visited the Pope in 1611 and recognized his jurisdiction and maybe the Union of Florence as well.
