Anti-suffragists
The scale of the campaign concerned those who didn't support women's votes, some of whom reacted with an anti-suffragist campaign.

The National League for Opposing Woman Suffrage
Some women actively campaigned against votes for women. These included the author Mary Ward (known as Mrs Humphrey Ward) who led the Women's National Anti-Suffrage League from 1908.
This organisation merged with the Men's League for Opposing Women's Suffrage in 1910, to form the National League for Opposing Woman Suffrage. Among its Presidents was the politician Lord Curzon.
