John Connelly is the Sidney Hellman Ehrman Professor of History at the University of California, Berkeley, where he currently directs the Institute for East European, Eurasian, and Slavic Studies. At the Academy, Connelly is exploring the long-term consequences of Germany’s emergence as a nation that was at once imperial and ethnic—a country that occupied a huge space in Central Europe and sought to make millions of diverse human beings into ethnic co-nationals.
