The suffragettes got frustrated because their cause was not being heard. So they took militant actions such as chaining themselves to railings, arson attacks and even bombings. Their targets were mainly institutions that symbolized male authority. The increasing violence of the campaign was partly due to the leadership style of the Pankhursts and partly to the frustrations of the campaign.
The militant campaign tactics of the suffragettes was used against them because many opponents claimed the use of violence showed women did not deserve the right to vote.
