An era was over and a new Europe was being born. This much was obvious. But with the passing of the old order many longstanding assumptions would be called into question. What had once seemed permanent and somehow inevitable would take on a more transient air. The Cold-War confrontation; the schism separating East from West; the contest between 'Communism' and 'capitalism'; the separate and non-communicating stories of prosperous western Europe and the Soviet bloc satellites to its east: all these could no longer be understood as the products of ideological necessity or the iron logic of politics. They were the accidental outcomes of history--and history was thrusting them aside. Europe's future would look very different--and so, too, would its past. In retrospect the years 1945-89 would now come to be seen not as the threshold of a new epoch but rather as an interim age: a post-war parenthesis, the unfinished business of a conflict that ended in 1945 but whose epilogue had lasted for another half century. Whatever shape Europe was to take in the years to come, the familiar, tidy story of what had gone before had changed for ever. It seemed obvious to me, in that icy central-European December, that the history of post-war Europe would need to be rewritten.
