A few short questions on something I've been thinking about for a while.
I've always wondered about Angkor, the city, the seat of power for the Khmer Empire. It seems so strange that such a large and magnificent city just faded and collapsed into oblivion. What would it have taken to see it survive in some discernible form into modern times?
Also, what would it have taken for the Khmer Empire to not have fallen into such a sharp decline?
