It is now twenty years since Communism trundled off to the dustbin of history. This makes for an exciting series of 20th anniversaries. The first partially free elections in an Eastern Bloc state were held in June 1989 in Poland, with Solidarity doing so well that the communists were thrown out of office (though a government was not formed until the 24th August).
Today makes for another interesting anniversary - it marks the day when Hungary began to stop policing its border with Austria. This made the country a conduit for East Germans who fancied heading to the West, setting in motion events that led to the opening of the wall and disappearance of the DDR.
