In 1846, the Society of Friends became the first officially registered and legal religious society outside the state church of Norway. It was not until 1956 that other groups (the Methodists and Lammers society) were registered in a similar way. Throughout the 1840s, Norwegian Quakers were subject to the Act Relating to Dissenters (1845), which was intended to keep dissenting groups in small, isolated pockets of Norwegian society. Despite this, Quakerism continued to spread, and new meeting houses were built in Kvinesdal, Sauda, Roldal, Skjold, and Tromsø during the 1840s. Still a relatively small population, Quakers numbered 473 in the 1865 census.
