To prove the earth was flat.
Conquestors such as Ferdinand Magellan for example, wanted to prove that the
Earth was indeed round. And Christopher Columbus (1450-1506) is an Italian crusader
who is tasked to look for Asia from Europe starting on the west direction. His
conquests during 15th to 20th century in Asia, Australia,
United States and Atlantic made new discoveries and colonies crediting him as
the explorer of the ‘New World’ or the ‘Age of Discovery’. His conquests were
very much celebrated however there also negative effects on the system instilled
on the newly-discovered places such as slavery, diseases, illiteracy, rape and
death.
