How did the Crusades help European exploration?

Answer 1

Trade and War

Answer 2

They didn't.

there are two different things you have on here...

First off, the Crusades was a waste of time and effert to try and conquer the Holy Lands, of course they failed miserabley at least 5 times

secondly, the Renaissance age was the part of the Midievel Ages where the study of art, and Astrology grew more and more, thus the age where Michaelangelo, Leonardo De Vinci, and Rapheal all got their fame. Not only all the artists but also Copernicus was proven wrong by Ptolemy about the sun revolving around the earth.

there fore, these two don't really have anything to do together.

Okay, this person who wrote the stuff above is correct, but I'll improve it :)

The Crusades helped the influence for exploration because they wanted to save the Holy Land. They then decided that they needed an all-water route to Asia. That's the reason.

Answer 3

The churches in Europe were corrupt and led the people to flee the European countries in hopes of religious freedom. By doing so, they found land. This also ties into the Renaissance, which pushed people to explore and provided new exploration tools.
