The Turkish diaspora (Türk diasporası or Türk gurbetçiler) refers to ethnic Turkish people who have migrated from, or are the descendants of migrants from, the Republic of Turkey, Northern Cyprus or other modern nation-states that were once part of the former Ottoman Empire. Therefore, the Turkish diaspora is not only formed by people with roots from mainland Anatolia and Eastern Thrace (i.e. the modern Turkish borders); rather, it is also formed of Turkish communities which have also left traditional areas of Turkish settlements in the Balkans (such as Bulgaria, Greece, North Macedonia, Romania etc.), the island of Cyprus, the region of Meskhetia in Georgia, and the Arab world (such as Algeria, Iraq, Lebanon, and Syria). In particular, most mainland Turkish migration has been to Western and Northern Europe. Meanwhile, almost all the Turkish minorities in former Ottoman lands have a large diaspora in Turkey, many having migrated as muhacirs (refugees); furthermore, the Cretan Turks have migrated throughout the Levant; Cypriot Turks have a significant diaspora in the English-speaking countries (especially the UK and Australia); the Meskhetian Turks have a large diaspora in Central Asia; and Algerian Turks and Tunisian Turks have mostly settled in France. Since Bulgarian Turks and Romanian Turks gained EU citizenship in 2007, their diasporas in Western Europe significantly increased once restrictions on movement came to a halt in 2012. Turks in Europe As early as 1997 Professor Servet Bayram and Professor Barbara Seels said that there was 10 million Turks living in Western Europe and the Balkans (i.e. excluding Cyprus and Turkey). By 2010, Boris Kharkovsky from the Center for Ethnic and Political Science Studies said that there was up to 15 million Turks living in the European Union. According to Dr Araks Pashayan 10 million "Euro-Turks" alone were living in Germany, France, the Netherlands and Belgium in 2012. Furthermore, there are significant Turkish communities living in Austria, the UK, Switzerland, Italy, Liechtenstein and the Scandinavian countries.
