Christabel Pankhurst was a pioneer in the use of militant tactics by the suffragettes. Instead of arguing in written or spoken word there was direct action. Women would heckle ministers at meetings and challenge them constantly with questions demanding to know why women should be denied the right to vote. If one suffragette was thrown out another took her place. Many women were expelled from meetings or arrested by the police.
Then the suffragettes began to take more radical steps, such as chaining themselves to the railings of houses belonging to MPs and ministers, and organising smashing of windows. Such militant tactics gained a lot of attention but also alienated potential supporters.
