Chilldoubt- unfortunately, I do not ha d the memory, nor education to be able succinctly summarise the major news events of the 20th century. I know that the 9/11 attacks happened in 2001, Princess Diana died in 1999, and that England won the World Cup in 1966. Beyond that, I'm pretty vague on national events.
But to me - 1933 is 'the thirties' and I associate that with the rise of the Blackshirts.
If the reference was to 1943, I would have thought of the Nazis.
I appreciate that the Nazi party was around in the thirties, I just don't associate them with that decade.
