The problem grew with the establishment of the modern Greek state in the 1820s when "foreign authors started to adopt the ‘Greek' slant on history, and started to use indistinct terms like ‘Ancient Greece' (even though that state never existed); the ‘Greek Peninsula' (instead of the Balkan Peninsula); ‘Greek letters' (even though the letters were known to be Phoenician); ‘Greek mythology' (even though this mythology belonged to all Balkan nations and other more distant counties) etc."
