Not to turn this thread too offtopic, another offtopic reply. If this discussion goes further, I'll just split it into another thread. Here goes.
a important case notheless cause the Aztecs had no united central administration and relied only on their miliatary power without a professional military.
I beg to differ. They had a very complex and effective administration, on most social matters. And most men were trained as warriors, or served in the military for a period of time. They were the frickin' Mesoamerican equivalent of Spartans.
I believe what you mean is that they didn't have an established command structure on the battlefield, which proved itself disastrous in the battle of Otumba, a battle miraculously won by the Spaniards by relying on their Tlaxcalan allies and capturing the Aztec commander in chief, causing most of the Mexica army to rout. But that one battle wasn't everything.
The Aztecs based their empire on military force, imposing heavy taxes over conquered lands. They expanded very rapidly, leading to an ever-increasing tax raise throughout some of their important vassals... which led to disgruntlement and even minor wars before the arrival of the Spaniards. The whole 'superior firepower/armor/cavalry' thing is overrated. The 500 conquistadores led by Cortes (Against the Crown's orders, I may add) would have been easily crushed by the Aztec army if it wasn't for the number of allies they eventually rallied against their Aztec opressor.
Furthermore, it wasn't as if Cortez landed and immediately brought the empire to its knees. He spent several months in Tenochtitlan before pillaging it with his men and fleeing, only to return later and conquer it after a very long and exhausting fight.
The conquista itself wasn't particularly bloody or cruel for the time's "standards". Bigger massacres happened in Europe during religious wars. Cortes and the few priests he had along didn't destroy a culture (arguably, it wasn't even 'destroyed' completely). It was the
encomienda system and an outbreak of several diseases that inflicted the biggest horrors and losses on the native population. Lastly, not all missionaries were power-hungry zealots, bent on torturing the native population for worshipping 'the devil'. Whereas most of them arguably were, a few notable and influential exceptions had place, such as Fray Bartolome De las Casas, and several other clergymen that preserved Aztec and Maya writings, instead of destroying them as was the norm.
On topic?
Why, you ask, Babs? Easy. Exploiting other peoples' fears for money and power has been Big Business since the dawn of time. Sure, several different religious institutions have made a lot of good things over time, although there's always someone, somewhere, that uses the power to his/her own benefit.
And with the widespread of mass media in a very rich country during the mid-20th century... it suddenly became
very easy to build empires on old ladies' checks.
