Midlarsky makes a compelling case on how territorial loss can produce political extremism and mass killing. This is a book not just about the past, but what we might behold in the future.' Paul F.

Monica Duffy Toft, Kennedy School of Government, Harvard University 'Midlarsky has produced an excellent, theoretically innovative, and empirically rich study.'
