How did nationalism promote unity in some lands and divisions in others? 2. Why did the expressions of extreme nationalism mark a repudiation of Enlightenment tradition and a regression to mythical modes of thought? 3. What is the relationship between medieval and modern anti-Semitism? How does anti-Semitism demonstrate the immense power of mythical thinking? Im studying for my test and my problem is that i think i know the answers but i am not completely confident about questions #1 & 2 and the first half of question 3? Please help me better understand this topic in words that i could comprehend.
