"The March of the Women" is a song composed by Ethel Smyth in 1910, to words by Cicely Hamilton. It became the official anthem of the Women's Social and Political Union (WSPU) and more widely the anthem of the women's suffrage movement throughout the United Kingdom and elsewhere. Activists sang it not only at rallies but also in prison while they were on hunger strike. Smyth produced a number of different arrangements of the work.
