The Spaniards had just spent 400 years getting the Muslims out of their country when they met up with the Aztecs.
That’s true-but it didn’t stop them from making war on someone in a country that wasn’t theirs-namely the Native Americans-I’m always amazed that it took the Spaniards so long to get the Muslims out of Spain/Al Andalus-even before the Romans came marching in, Celts had settled there-not a peaceful bunch-then you add Roman DNA over a few centuries and you’ve got a country full of mean sonsofbitches-it was an accident of nature that the Muslims didn’t get thrown out years before El Cid came along,,,
