On 6 November 1867, the National Society for Women’s Suffrage was formed, as the first organization to advocate at the national level for women’s right to vote in the history of the United Kingdom. This event, among others, may symbolize the beginnings of the women’s suffrage movement (even if it had remained mostly decentralized and globally weak during the Victorian era) which was noticeably supported by J. S. Mill and Harriet Taylor.
