The motives of exploration during the age of discovery during the 16th century were really important for the people living in that century. There were different kind and plenty of motives to choose from. Some of the motives are glory, greed, god, political/economic competition. Glory was the desire of wealth. It was more like a personal fame. Greed was the search for spices and gold. The motive god was to win as many converts possible to Christianity. The motives of exploration were like the opening doors for the trade that started all around the world. Exploration during the age of discovery led to European economic dominance. As you know, European began to explore for a variety of reasons. The most significant reason was greed, the search for spices and gold, because almost everyone was looking for spices and gold and also finding routes to Asia and India for spices and gold, and explorers make that their top priority. I think they could also achieve these other goals or motives by this one. Because if they have a lot of spices and gold, they can achieve motives like glory. They can do much more with it.
The search for wealth was the most important motive because so many people were looking for this motive. They wanted as much spices and gold as they could possibly find. For example, Christopher Columbus was trying to find a route to Asia to get gold.
Christopher Columbus was born in Italy in the Italian seaport of Genoa in 1451. He was an Italian mariner and outstanding navigator and organizer of expeditions, widely believed to be the first European to sail across the Atlantic Ocean and successfully land on the American continent. He achieved fame by sailing west across the Atlantic Ocean in search of a sea route to Asia. But he did not accomplish this goal. Instead, he encountered islands in the Caribbean Sea. At that time, the people of Europe and the Americas did not know of each other's existence.
