Anti-Turkish sentiment
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.
