Marcin Dunin was Archbishop Metropolitan of Gnesen and Posen and Primate of Poland from 1831 to 1842. When he took the episcopal sacraments on July 10, 1831, he was considered by the Prussian authorities to be loyal to them. This changed in 1837, when the archbishop, based on Pope Pius VIII's breve of 1830, demanded that the faithful in Catholic-Protestant marriages raise all their children in the Catholic faith, while the Prussian authorities' policy was that sons should adopt their father's confession and daughters their mother's. The conflict led to his imprisonment in the Kolobrzeg fortress, from which he was released by order of King Frederick William IV. Martin Dunin wrote a devotional booklet, which was referred to as Dunin.
