The fall of the wall, plus 20

The autumn of 1989 was an exciting time to be teaching political science, due to the extraordinary events occurring in the former east European Soviet bloc. The culmination was, of course, the dramatic opening of the Berlin Wall on 9 November. A political illusion that had seemed so immovable for four decades collapsed with unprecedented swiftness over the course of a very few weeks. By Christmas it was all over, and a new era had begun. To my current students, of course, this is all ancient history, of which they have no memory.
