This looks yet again as a CNN version of the "truth". Muslim wars in Spain from 1711-1492 was "religious wars had been tough..."
Sout America as "untouched" even though those tribes had been murdering eachother and building cities with millions of people now revealed with LIDAR. How is that "untouched"?
Since this is new one can also provide the proof of Piri Reis map from the 1500's that has Antarctica (how the coastline looks like without ice) and the whole South America coastline in it. Beeing proof to other older maps and history that travelers and cartographers could have taken their ideas from. Just as Columbus said and therefore asked for the finances for explorations. This is yet again the mainstream version to make Europeans evil again and not very factual at all.... So naming the tagline of this series with something with "truth" is exactly the word a very honest person would NOT use. This is the same propaganda as "trust the science" "don't question anything"
