Fall of Civilizations

I found the stories of decline so compelling and often overlooked. I'm curious whether this focus was driven by a particular interest or research challenge.

The depth varied between chapters, which made me wonder if it was due to available sources or the author's personal interests. Did others notice this imbalance?

The selection process must have been tough given the breadth of history. I'm interested in whether some lesser-known civilizations were considered or if certain stories were prioritized for a specific reason.
