The article is utter, total BS.
Columbus, as you’ll recall, was trying to find a trade route to the west indies which was... wait for it... ISLAMIC AT THE TIME.
This author seems to be willfully ignorant about the “European Crusades” The Crusades were a response to Islamic aggression. The goals was to RE-CAPTURE the Holy Land from the Muslims for the Byzantine Empire
It is true that Europe was looking for ways to fund its wars against Islamic, because it was trying to free itself from Islam.
That part is true. But that’s about the only part.
I think you meant East Indies? And not all of the East Indies were under Muslim rule. There was also the China opportunity.
And yes, Muslim control of the Med, Egypt, the overland Silk Route was the impetus for da Gama’s voyage around Africa and Columbus’s voyages westward.
