I was working on my Behavioral Science assessment and came across some interesting facts about Tibetan cultural history....
Prior to the Chinese government changing laws in the 1960's, it was common for a woman in Tibet to marry a set of brothers. This allowed the family to receive maximum use of their land (without splitting it between heirs). Parents on either side would seek an arrangement that was mutually beneficial.
My husband were discussing the practicalities of this. And he felt since marriage was primarily viewed the vehicle to produce children/status, there wouldn't be the same problems we'd might experience with sharing spouses.
I, on the other hand, was thinking more along the lines of getting pregnant and having to birth sons by several different brothers (I'll pass!).
I even wondered if there were concubines for sexual pleasure, so the wife didn't carry all of the "burden". I'm just saying...
But upon further research, I found that oftentimes only one husband would be home at a given interval. The men were prone to long trips, so a woman with three husbands, could go years with only one of them on the family land.
It's interesting how religion, cultural norms, and geographically circumstances influences values/practices.
