Norway has in a relatively short time developed from a fairly homogeneous society with deep roots in Lutheran-Protestant norms and traditions into a multicultural and pluralistic society. Even though there appears to be a correlation between transnational marriages, immigration law and the legal challenges that these transnational marriages may pose, this potential tension is not the main reason why transnational marriages and divorces between Muslim spouses seem to cause problems in European legal systems, including Norway. In comparison with other European countries, migration from Muslim countries started rather late in Norway. During the late 1960s, the first groups of Muslim migrants began coming from countries such as Pakistan, Morocco and Turkey to perform low-skilled and low-paid labour to financially support their families at home and to make investments in their country of origin. In contrast to the private international law of many other European countries, Norwegian private international law follows the domicile principle.
