It's 1453 CE; the Portuguese have already discovered several islands and are exploring routes along the African coast when the Ottoman Empire gains control of Constantinople. Soon after, the major European trade routes are blocked, causing the trade via North Africa and the Red Sea to diminish significantly. In desperation, Europe looks outward. Instead of focusing on land-based trade routes, they start to explore other options to carry out their trade. This exploration was one of the main factors that started the Age of Discovery.
The Age of Discovery
Over the following two centuries, Europe expanded its influence around the world. What started out as a search for new trade routes soon became a search for new worlds. They discovered that the earth was much larger that what they had previously believed, and the discovery of new places and people caused them to send more and more ships out across the oceans. Jonas Bush observes in, "
Exploring Our Lives," that "
they [the explorers] had a burning drive to discover new things and bring themselves glory, wealth, and success."

Previously, exploration by ship generally took place near coastlines, never venturing into the unknown. But this changed when Christopher Columbus set out to find a western route to India, leading him to discover the Bahamas instead.
After it was revealed that there were new worlds, more rulers began to send voyagers to discover and claim these lands for themselves. Portugal claimed Brazil; Spain conquered Mexico, Chile, and Argentina; and England eventually established a colony in the United States.
America
Now while all these voyages and discoveries had good and bad about them, it was crucial that they happen for us to be able to live in these countries today. Discovering new worlds opened up countless doors that have led the way to new developments and dis
coveries over the centuries. And while all the worlds that were discovered were important, I think that the discovery of the United States was an irreplaceable event.
