In Norway, Sikhism has approximately 5,000 adherents, mostly living in Oslo.
In 1969, the first Sikh who arrived in and settled in Norway was Amarjit Singh Kamboj.
The troubles in Punjab after Operation Blue Star and riots committed against Sikhs in India after the assassination of Indira Gandhi led to an increase in Sikh refugees moving to Norway and other countries.
[citation needed] Drammen also has a sizeable population of Sikhs; the largest gurdwara in north Europe was built in Lier.
[citation needed] To increase knowledge of Sikhs and their culture, a professor of science of religion, Knut A. Jacobsen, who works in the University of Bergen, published a textbook titled Sikhismen: historie tradisjon og kultur,[4] in Norwegian for schools.
