Emmeline Pankhurst
Emmeline Pankhurst, along with other prominent feminists like Susan B. Anthony, Sojourner Truth, and Mary Wollstonecraft, was a key figure in the first major feminist rallying cry. Emmeline Pankhurst created The Women's Political and Social Union (WSPU) in 1905, a women-only organization with the slogan 'Actions, not words' after her husband's death.
After that, Emmeline Pankhurst and other Suffragists in the United Kingdom had campaigned strongly for the advancement of women's rights and, especially, the ability to vote throughout the years. After the now-famous WSPU protest in London in 1906, Emmeline Pankhurst published her profound words, "Women have always worked for men and their children. They were now willing to battle for their own civil rights."
And all of her efforts and sacrifices paid off. Seven years later, in 1918, women all around the country finally won the right to vote as a result of Pankhurst's Suffragette campaign, nonviolent and radical speech, and seminars. She has become an inspiration for lots of modern feminists today.
