Answer:
Step-by-step explanation:
In my opinion I think that the most important thing that changed the world between the 1400-1800 was travel. At that period of time there were many expeditions being launched, one of the most famous would probably be Christopher Columbus expedition to the americas. These expeditions changed the way the people thought of the lands beyond the shores, many people started going to the americas in order to be free or practice their religion freely, and if it was not for these expeditions we certainly we would not have ever discovered the americas. To the europeans the discovery of the americas was an excellent discovery as it opened a door to an abundance of resources that triggered global advancements in many fields such as mathematics and sciences.
