The Romans very specifically invaded what we today call Britain because the people who lived there were matriarchal. I am Cherokee, my tribe was also matriarchal before white people showed up. In my tribe, traditionally, when you get married your possessions belong to your wife and you join the clan of your wife.

Patriarchy has never been as widespread as patriarchs would like you to believe.

Both are true - Roman society is patriarchal in a particular way, e.g women were known by their fathers name (e.g Agrippina Claudius is daughter of Claudius) and considered almost like property of their father, until they were married off to a husband, and were henceforth known by their husbands name.

Sound familiar? That's basically what Atomicbocks is referencing
