Contacts with the Muslim world dates back to the 7th–10th centuries, when the Vikings traded with Muslims during the Islamic Golden Age. Since the late 1960s and more recently, immigration from predominantly Muslim countries has impacted the demographics of religion in Sweden, and has been the main driver of the spread of Islam in the country.

Immigration to Sweden is the process by which people migrate to Sweden to reside in the country. Many, but not all, become Swedish citizens. The economic, social, and political aspects of immigration have caused some controversy regarding ethnicity, economic benefits, jobs for non-immigrants, settlement patterns, impact on upward social mobility, violence, and voting behaviour.
