Anti-Turkism, also known as Turkophobia or anti-Turkish sentiment, is hostility, fear, intolerance, or racism against Turkish or Turkic people, Turkish culture, Turkic countries, or Turkey itself.
The term refers to intolerance not only against the Turks of Turkey, but also against Turkic groups as a whole, including Azerbaijanis, Crimean Tatars, Turkmens, Bulgarian Turks, Macedonian Turks, Turkish Cypriots, Bosnian Turks, Meskhetian Turks, Turks of the Dodecanese, Kosovan Turks, Croatian Turks, and Romanian Turks, Turks in Iran. It can also refer to racism against Turkish people living outside of Turkey following the Turkish diaspora.
The roots of anti-Turkism can be traced back to the arrival of the Huns in Europe. While the ethnic background of the Huns is a matter of dispute among historians, they are widely believed to have been of Turkic origin, and their invasion inspired fear among Europeans.
In the Late Middle Ages, the fall of Constantinople and the Ottoman wars in Europe—part of European Christians' effort to stem the expansion of the Ottoman Empire, the predecessor to Turkey—helped fuel the development of anti-Turkism. By the middle of the 15th century, special masses called missa contra Turcos (Latin for "mass against Turks") were held in various places in Europe to spread the message that victory over the Ottomans was only possible with the help of God and that a Christian community was therefore necessary to withstand the cruelty of the Turks.
