The European migrant crisis, or the European refugee crisis, is a term given to a period beginning in 2015 when rising numbers of people arrived in the European Union (EU), travelling across the Mediterranean Sea or overland through Southeast Europe. These people included asylum seekers, but also others, such as economic migrants and some hostile agents, including Islamic State militants disguised as refugees or migrants.
Most of the migrants came from Muslim-majority countries of regions south and east of Europe, including Western Asia, South Asia and Africa. By religious affiliation, the majority of entrants were Muslim (usually Sunni Muslim), 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%).
Of the migrants arriving in Europe by sea in 2015, 58% were adult males over 18 years of age, 17% were adult females over 18 years of age and 25% were minors under 18 years of age. The number of deaths at sea rose to record levels in April 2015, when five boats carrying almost 2,000 migrants to Europe sank in the Mediterranean Sea, with a combined death toll estimated at more than 1,200 people. The shipwrecks took place in a context of ongoing conflicts and refugee crises in several Asian and African countries, which increased the total number of forcibly displaced people worldwide at the end of 2014 to almost 60 million, the highest level since World War II.
