It appears that this was a conscious effort on the part of Calakmul to bring about the collapse of Tikal's southern allies.

Increasingly endemic warfare in the Maya region caused Tikal's supporting population to heavily concentrate close to the city itself, accelerating the use of intensive agriculture and corresponding
