Peasants in the re-taken Somme District work in the fields, circa 1916- 1917, in this Library of Congress handout photo.

As the 20th century progressed, hard-won progress included gradually improved voting rights, while the upheaval of war pushed doors ajar as women worked as part of the war effort.
