While it has historically been the Aztecs who were viewed as a militaristic civilization, there is considerable debate among scholars on the question of territorial aggression among the Maya. Since many of the Maya cities lack fortifications that are like those that Western archaeologists might have expected, it was once assumed that the Maya created for themselves an ideal, pacifistic society. However, others have theorized the Maya were particularly ferocious in warfare, taking captives for ritual sacrifice and appropriating territories through force. Still others have explained the demise of certain Maya cities by arguing that they were devastated by internecine warfare that doomed both sides of the fighting.
As with many aspects of Maya society, the presence or absence of bellicose behavior is an enigma. There have been some findings of parapets and ramparts, in particular at Tikal and Becán, clear proof that the Mayans saw the need for defensive fortifications for those cities. At the same time, the fact that such ramparts were not a consistent part of Maya city construction is evidence that there was considerable variation in aggression, expansion and cooperation from one city to another.
Today, it is a commonly held belief among scholars that warfare between Maya cities erupted when there was a shortage of food, either because of drought or insufficient production to support an expanding population. Although there is no direct evidence, it is supposed that one city would expand into the territory of another, sparking a competition for land.
