I read an interesting article about the Suffragettes a few years back and the basic theme it covered was actually that their movement, whilst undoubtedly drawing attention to the inequality in the country at the item (which was a good thing, obviously), actually did very little to change the situation.
After all, consider for a moment you are a gentleman of the early 20th century who believes that women are weak creatures who need to be kept in their place and that giving them the vote would be a fanciful notion - would you suddenly change your mind because a group of them broke some windows, set off bombs, vandalised art or started throwing themselves under racehorses? Of course you wouldn't - if anything it would reinforce your feeling that they are too emotional and couldn't think as logically as men.
Said article suggested that what actually gave women equality was the First World War -the men went off to fight and the women took their jobs in the factories and actually proved through actions that not only were they just as capable as the men, in some cases they were better. This was in strong contrast their earlier militant actions, with the suggestion that these did more harm to their cause than good.
