I'm not sure about that, but it could be linked. What I perceive about empires as opposed to entire populations is that it is almost inevitable there is a ruling class and a subservient class, but the ruling class become so insular and self-serving that eventually they squeeze the subservient class beyond endurance. Once there is a revolution the populace becomes leaderless and ungovernable, so the civic system becomes dysfunctional.
Naturally, if resources become inadequate to support an expanding populace, the ruling classes still want their customary levels of comfort so that contributes to the squeeze.
Ruling classes only rule by popularity or force. Enforcement requires the backing of those willing to act as enforcers, who demand their cut. Popularity requires providing the populace with adequate levels of comfort. Neither of those work if resources become limited.
