Sámi people of Norway
Regarding getting the Sami to change their religion to Christianity: In the 18th century Thomas von Westen, a pietist, led missionary work (among the Sami), that has been called a  concerted (or special) effort. "About a century later, Niels Vibe Stockfleth worked among the Sami and translated [the Bible's] New Testament into" [one of the Sami languages].
