The Suffragette movie is very thought provoking. Meryl Streep plays an important character, Emmeline Pankhurst, but it isn't a huge part. It's Carey Mulligan's character whose fictional story is followed throughout the movie who carries the story. I've never taken the cause lightly as I lived in London next door (as a child) to a woman who had once been a suffragette and she told me some of the horrific stories of how women were treated. Emily Davison is also portrayed in the story. No one really knows if she intended to be killed that day by the King's Horse or whether she merely wanted to disrupt the race at the Epsom Derby and bring attention to the Suffragette Movement. Herbert Jones, the jockey, was unconscious after the collision, but survived.
The 1918 Representation of the People Act allowed women of property over the age of thirty the right to vote.
