Some of the earliest attempts to organize Islamic worship in Norway was done by labor organizations as early Muslims were labor migrants. The first mosque was established in 1972 by Pakistani immigrants. Another mosque, the Islamic Cultural Centre (ICC) opened in Oslo in 1974. The initiative for the mosque came from Pakistanis who were helped by the Islamic Cultural Centre which had already opened in Copenhagen in Denmark. The new mosque adhered to the deobandi branch of Sunni Islam. Adherents of the Sufi inspired Barelwi movement, who constituted the majority of Pakistanis in Norway, soon felt the need for a mosque of their own, and opened the Central Jamaat-e Ahl-e Sunnat in 1976. This is today the second largest mosque in Norway, with over 6,000 members. The first Shia mosque, "Anjuman-e hussaini", was founded in 1975, and until 1994 was the only Shia congregation. The Tablighi Jamaat came to Norway in 1977. An Albanian mosque was established in 1989, and a Bosnian mosque in the 1990s. Until the 1990s, mosques and Islamic organizations in Norway were established along ethnic lines. Such establishments were by immigrants from Pakistan, Turkey, Morocco, Arab world, Somalia, The Gambia and Bosnia.
