The post-World War II migration of Arabs to Europe began as many Arabs from former French colonies like Algeria, Morocco, Tunisia, Lebanon and Syria migrated permanently to France. Another source of migration began with "guest workers", particularly from Morocco, who arrived under the terms of a "Labour Export Agreement" between several European countries including Germany, Spain, the Netherlands, Belgium, Austria and France. Other events in the Arab world sent new immigration waives to Europe like the Palestinian exodus, the Lebanese Civil War, the first and second Iraq War, Libyan Civil War and Syrian civil war. Many other Arabs emigrated to Europe because of political issues in their native countries. Arabs who studied in European universities and decided to stay are another source of migration.
