What were the conditions in Europe that led to the conquest of the Americas?history

The major condition in Europe that led to the original
conquest of the Americas was peace.  This applies mainly to Spain which, of course, was
the country that was first involved in conquering the New
World.

Spain came to be able to explore because of the
coming of peace.  Up until 1492, the Spanish had been involved in wars against the
Muslims, trying to push them out of the Iberian Peninsula.  But then the Spanish won
that struggle and were at peace.  At that point, they were able to put their money
towards exploration.  Once Columbus "discovered" the New World, the Spanish were able to
send soldiers to conquer who were no longer needed for wars in Spain
itself.
