European migrant crisis

The European migrant crisis, or less precisely European refugee crisis, began in 2015 when rising immigration numbers of illegal immigrants arrived in the European Union (EU), travelling across the Mediterranean Sea or overland through Southeast Europe. These unauthorized foreign migrants encompassed not only asylees seeking to apply for refugee status and the right of asylum in claims to be individually determined as genuine or not, but also encompassed various others, such as economic migrants and a small number of hostile agents including "Islamic State militants".

The unauthorized foreign migrants came mostly from Muslim-majority countries of the regions of Western Asia (Middle East), South Asia, Africa (North Africa and Sub-Saharan Africa), and Western Balkans. By religious affiliation, the overwhelming majority of entrants were Muslim (including Sunni Muslims, but also non-Sunni minorities), with a small component of non-Muslim minorities (including Yazidis, Assyrians, Mandeans, etc.). According to the United Nations High Commissioner for Refugees, the top three nationalities of entrants of the over one million Mediterranean Sea arrivals between January 2015 and March 2016 were Syrian (46.7%), Afghan (20.9%) and Iraqi (9.4%), all overwhelmingly Muslim entrants.
