The nomadic Inuit peoples were traditionally shamanistic, with a well-developed mythology primarily concerned with propitiating a vengeful and fingerless sea goddess who controlled the success of the seal and whale hunts.
The first Norse colonists were pagan, but Erik the Red's son Leif was converted to Catholic Christianity by King Olaf Trygvesson on a trip to Norway in 990 and sent missionaries back to Greenland. These swiftly established sixteen parishes, some monasteries, and a bishopric at Garðar.
Rediscovering these colonists and spreading the Protestant Reformation among them was one of the primary reasons for the Danish recolonization in the 18th century. Under the patronage of the Royal Mission College in Copenhagen, Norwegian and Danish Lutherans and German Moravian missionaries searched for the missing Norse settlements and began converting the Inuit. The principal figures in the Christianization of Greenland were Hans and Poul Egede and Matthias Stach. The New Testament was translated piecemeal from the time of the very first settlement on Kangeq Island, but the first translation of the whole Bible was not completed until 1900. An improved translation using the modern orthography was completed in 2000.
Today, the major religion is Protestant Christianity, mostly members of the Lutheran Church of Denmark. While there is no official census data on religion in Greenland, the Lutheran Bishop of Greenland Sofie Petersen estimates that 85% of the Greenlandic population are members of her congregation. There are still Christian missionaries on the island, but mainly from charismatic movements proselytizing fellow Christians. The first reported Muslim in Greenland, Wassam Azaqeer, made headlines around the world when he observed Ramadan north of the Arctic Circle, requiring him to fast for 21 hours at a time
