Alice Maud Arncliffe Sennett also known with the stage name of Mary Kingsley was an English actress and suffragist and a suffragette, arrested four times for her activism.

The United Procession of Women, or Mud March as it became known, was a peaceful demonstration in London on 9 February 1907 organised by the National Union of Women's Suffrage Societies (NUWSS) in which more than 3,000 women marched from Hyde Park Corner to the Strand in support of women's suffrage. Women from all classes participated in what was the largest public demonstration supporting women's suffrage seen until then. It acquired the name "Mud March" from the day's weather since incessant heavy rain left the marchers drenched and mud-splattered.
