Yes, Canary , women getting the vote was a lot to do with the Great War but the suffragettes had demonstrated such fervour before it that, come the time,the argument was very strongly reinforced. Otherwise the government of the day could have gone the old sweet way. It couldn't face more militancy and by then the public begun to accept the pre-war argument that women had, and could handle, responsibility.
Note that, essentially, only women of 30 or more could vote. This seems to have been to bring equality of numbers in an election, since, by 1918, men below 30 were far less numerous than normal. Women only got equality in 1928, which was the very year that Mrs Pankhurst died, I think.
By the way, FredPuli bid and paid for the scarf, now in the Houses of Parliament, at auction, but is used to being left out of the narrative; well, I did eventually treat it as a gift to my now ex. What rankles is I'm still waiting for the knighthood she said she'd fix. LOL
