When reading about the end of the Tibetan empire, information about the political situation of the area is scarce (most authors focus a lot on the religion).
Basically, who was de facto or de jure in charge of its regions? The buddhist monastic schools?
Thanks in advance.
EDIT: Maybe I wasnt't too clear, sorry for that. I want to know the political landscape of Tibet at the time. I know there was no single power looming over it, but which were the most influent imperial houses and religious schools?
