Before 1918 only men were allowed to vote in parliamentary elections. In the early 20th century there were two main groups active in the campaign for women's suffrage, a term used to describe the right to vote.
These two groups were the 'suffragists' who campaigned using peaceful methods such as lobbying, and the 'suffragettes' who were determined to win the right to vote for women by any means. Their militant campaigning sometimes included unlawful and violent acts which attracted much publicity.
