Which South American country achieved independence without violent revolt?
s344n2d4d5 [400]

Answer:

C. Brazil

Explanation:

The South American country that managed to achieve independence is actually the largest and most populous country, Brazil. Brazil has been established as a Portuguese colony during the Age of Exploration.

The Portuguese saw what is now Brazil as an excellent territory for making a colony where large plantations of cash crops will be established, thus to make lot of wealth from them. That functioned well for some time, but the authorities in Brazil gradually started to become more and more powerful.

With the colony slowly becoming more and more independent, and the population growing rapidly and surpassing the one of Portugal, Brazil decided that it wanted to be independent. While the Portuguese were not fond of this idea, they saw that it would be impossible for them to win a war with Brazil at that time, so the independence was gained through negotiations.

Portugal and Brazil kept close thighs and good relations, and still do.
