 On the orders of the Norwegian king Olaf Tryggvason, Sigmundur forced the island people to convert to Christianity in 999.Resistance to the new religion led by the notorious Tróndur í Gøtu was quickly suppressed, and even though Sigmundur himself lost his life, Christianity gained a foothold.About one hundred years after the introduction of Christianity, the Faroese church joined the Roman Catholic church, with an episcopal residence in Kirkjubøur and subject to the archdiocese of Nidaros (Tróndheim) for most of the time.
