History is not a long series of centuries in which men did all the interesting/important things and women stayed home and twiddled their thumbs in between pushing out babies, making soup and dying in childbirth.
History is actually a long series of centuries of men writing down what they thought was important and interesting, and FORGETTING TO WRITE ABOUT WOMEN. It’s also a long series of centuries of women’s work and women’s writing being actively denigrated by men. Writings were destroyed, contributions were downplayed, and women were actively oppressed against, absolutely.
But the forgetting part is vitally important. Most historians and other writers of what we now consider “primary sources” simply didn’t think about women and their contribution to society. They took it for granted, except when that contribution or its lack directly affected men.
This does not in any way mean that the female contribution to society was in fact less interesting or important, or complicated, simply that history—the process of writing down and preserving of the facts, not the facts/events themselves—was looking the other way.
