Twitter notes on inheritance & gender
Well, under Empress Grandma, the country had a major renaissance of innovation: a blue dynasty. Emperor Now~~~is a Red dynasty, very warlike, using Grandma’s infrastructure to conquer the Southern People. Buuut because of the ~~way inheritance works, Empress Grandma’s time was a very restrictive time for women, while Emp.Now is not.
The 1st-of-1st, 3rd-of-3rd, 9th-of-9th etc. child-of-child, of Gender Opposite Monarch, are heirs. I.e.~~~~Emp.Now’s 1st daughter’s 1st daughter, his 3rd daughter’s 3rd daughter. He was Grandma’s 9th son’s 9th son.
Inheritance by the women’s lines doesn’t require knowing who the father is, thus less sequestering of mothers.
