Women contributed more than history will ever give them credit, especially in a patriarchal society as was America in her beginning.
Did you ever hear of Mercy Warren? Most people haven't, but she was an influence on the Founding Fathers and played a part in the wording in the Constitution. Abigail Adams was also a prominent figure of her time, but history does not tell of us the extensive letters she wrote and the impact she had on our nation.
You should do a little research on the famous woman who had an impact on America. Margaret Brent, Mary Musgrove, Elizabeth Blackwell, Mary Baker Eddy, Clara Barton, Pocahontas, Sacajawea, the list goes on, but women could only do what they were allowed to by the restrictions place on them by men.
