Born on 15 July 1858, Emmeline founded the Women's Social and Political Union (WSPU) in 1903 and initiated a series of political interventions, including smashing windows, assaulting police officers and even arson.
The vote was extended to women over 30 (if they or their husbands occupied premises of a certain value) in 1918, and then to all women over 21 in 1928.
Unfortunately Emmeline did not live to see the change her campaign helped to generate. She died a few weeks before legislation was changed, aged 69, on 14 June 1928.
Google have chosen to honour Emmeline's birthday with the above homepage doodle. We're joining in the celebrations by bringing you the best quotes from this remarkable woman.
