Why might an author or speaker refer to columbus's voyage to america as an "invasion" rather than a "discovery"?

The correct answer is "invasion".

Explanation:

Many historians refer to Columbus's voyage to America as an "invasion" instead of a "discovery" because land was taken by force.

Some people regard the Spanish conquer as a "genocide" since the original inhabitants were killed. Those who survived were forced to acquire a new language, a new religion (they were forced to change of God), and new customs.  

a) the colonists began to see themselves as different from people in britain.

the correct answer is: the fact that the anti-federalist papers were considered poorly written.
