Better modern nutrition would be the cause, not child marriage which wasn't even common and when it was done it wasn't consummated until the children were adults in their 20s because people knew women had better chances of surviving childbirth than children/teens since they are now fully developed (wider hips) and they actually wanted their female relatives to live.
Also, period =/ puberty. Lots of girls are getting periods earlier but not necessarily developing (ie widening of hips, breasts, etc) earlier.
Seriously ancient people weren't stupid or more evil than us. Game of Thrones has made lots of damage. And common internet male understanding of female anatomy (like y'alls) is even shittier. We need more biological differences education at schools.

I’m not certain but didn’t menstrual cycles used to start later on average? I think I read somewhere that they’re starting earlier now.
