Beginning with Christopher Columbus' initial voyage in 1492, the Spanish began exploring, conquering, and colonizing the Americas. The Portuguese, having their own growing Empire across Asia and Africa, sought Papal advice on which king could rule which areas. The Treaty of Tordesillas drew a line in the Eastern portion of South America, which gave everything west to Spain and east to Portugal. Thus, the only portion of South America settled by the Portuguese was Brazil.

Columbus' original mission was to find a passage across the Atlantic to establish trade routes with the Far East. When Columbus arrived in the Carribean, he thought he was in the East Indies (hence the use of the term "Indians" for the indiginous people of the Americas). Later Spanish missions would attempt to establish colonies and spread Christianity.

Columbus' expeditions were funded by the Spanish king and queen, Ferdinand and Isabella.

Hernan Cortes and Francisco Pizarro were both Spanish Conquistadors who arrived in South America in the sixteenth century. Using similar tactics that relied on superior weaponry and manipulating old tribal rivalries, Cortes and Pizarro were able to tear down the two largest civilizations—the Aztecs (Cortes) and the Inca (Pizarro)—in what is now called Latin America.

Driven by the promise of rich reward, they sacrificed the lives of hundreds of thousands of Native Americans and mined deep into the heart of the South American continent. In one way, they were succesful—the amount of gold and silver they flooded into the European market was unprecedented; however, in the long term, the result was almost as bad for Spain as it was for South America. The Spanish companies and individuals owed so much debt to British and Dutch investment banks and companies that the profit ended up in the hands of others and the price of gold and silver in Spain plummeted.

All of these individuals were involved with Portugese exploration except for Christopher Columbus, who was actually born in Italy but sailed to the New World under the patronage of the Spanish monarchs Ferdinand and Isabella.
