The Patriarchy was invented by king fritz in which all true women were abducted and forced to serve as lesser people. It began with those women carrying sticks and harvest for pleasure and large stones usually. The kingdom of eldia was the second kingdom of humanity and king fritz challenged the first country uul to a battle of wits. Uul was victorious so it is possible to join the patriarchy sometimes instead of descendant only. I Uul who was Eren Jager became The Owl of Eldia and The Final Patriarchy.

I won't be pushed aside, I will be heard
I will get what I want
