Icelandic annals relate the arrival of embassies from the Muslim sultan of Tunis in Norway in the 1260s, after King Håkon Håkonsson had sent embassies to the Sultan with rich gifts. The population of Muslims in the country has not been noticeable until the latter half of the 20th century, however. By 1958, Ahmadiyya missionaries had attracted a small number of converts and established a small community in Oslo. Immigration from Muslim countries to Norway began late compared to other western-European countries, and didn't gather pace until the late 1960s. However, due to the oil boom, labor migration lasted longer than other countries. The first Pakistani immigrant laborers arrived in 1967. In 1975, labor immigration to Norway was halted, but rules for family were relatively relaxed for several more years. As a result, while most immigrants until the 1970s were laborers, immigration in the 1980s and 1990s was dominated by asylum seekers.
