In 1441, however, discontented with the absence of strict discipline in his community, he obtained the leave of the papal legate at the council of Basel to transfer himself to the Carthusians, entering the monastery of Salvatorberg near Erfurt, of which he became prior.
The Carthusians were expelled in 1782 by the emperor Joseph II., and after being held by the Cistercians in 1784 and the Carmelites in 1789 the monastery was closed in 1810.
In 1843 the Certosa was restored to the Carthusians and was exempted from confiscation in 1866, but it has since been declared a national monument.
James had already threatened the Benedictines and Augustines for " impudently abandoning religious conduct," and had founded the Carthusian monastery in Perth, that the Carthusians might offer a better example.
But the recognition of the royal supremacy could only be enforced at the cost of the heads of Sir Thomas More, Bishop Fisher and a number of monks and others among whom the Carthusians signalized themselves by their devotion (1535-1536).
