"There is no country in Europe which does not have in some corner or other one or several ruined fragments of peoples (Völkerruinen), the remnant of a former population that was suppressed and held in bondage by the nation which later became the main vehicle of historical development. These relics of a nation mercilessly trampled under foot in the course of history, as Hegel says, these residual fragments of peoples (') always become fanatical s of counter-revolution and remain so until their complete extirpation or loss of their national character, just as their whole existence in general is itself a protest against a great historical revolution."
