Check out the Women's suffrage parade of 1913 on mail online.
Many women rode their horses astride or used their carriages.
Over a hundred women were injured by men shoving them down or tripping them! I admire their bravery,I wish I could have been there!
Note the date for that parade in Washington: March 3, 1913; the day before Woodrow Wilson's inauguration.
Wilson was against women's right to vote in the first election, which is why suffragettes chose his inauguration as the focus of their march. Some of the organizers literally walked/rode from NY to DC, arriving for the march on the day before the inauguration. The march ended in violence with over 200 women seriously injured and many imprisoned. Those in jail for this and other protests were frequently beaten and tortured.
Wilson changed his mind on the issue during his re-election in 1918. Women's contributions in WWI made it difficult to continue to deny them the vote. The 19th Amendment was ratified in 1920 - 7+ years after the march on DC.
The road to justice was long and as the photos reveal, the horses did their part (keeping it horse related).
Alice Paul - shown in the second photo in the link that Muggle Mom provided - was a member of my family, albeit a lateral line (her 2 brothers married 2 sisters in my direct line - all living in NJ). She was an extraordinary woman - a Quaker who was very dedicated towards returning the vote to women. According to one genealogist in her direct line, she was a real hoot, too. I loved hearing the personal stories about her, and have always been proud to point to her as an (in-law) relative.
Don't forget - women who owned land, just as men who owned land, had the right to vote in NJ before those slimebag NJ legislators - William Griffith and John Condit - successfully aruged for the proposal in 1807 to yank the right to vote from woman and the colored population, regardless of their status as land holders, and keep it just for white males. If I ever find out where those pompous a-holes are buried, I'm going to spit on their graves.
