What is patriarchy?

Feminists who blindly follow the narrative (the agenda that destroys the lives of both men and women, and uses our own money while doing so) always claim there was some kind of patriarchal agenda that deliberately put men before women, what do they even mean by that?

Were men in feudal syatem, or even slaves somehow privileged compared to women? And would any women really want to live today like they did in the middle ages or antiquity?
