White VS. Black
Which side haves more rights.
During the time of Age of Exploration, a lot of racism started between blacks and whites. Slavery even began before the Spaniards or Portuguese or any other type of raise. Africans used to trade or capture slaves for power or in their lands. There is still racism these days too, but it slowed down a lot thanks to Martin Luther King with his "I had a dream" speech. Africa's queen tried to stop the Portuguese from conquering their land and taking her people as slaves which did happen but the queen escaped before she was captured and took as a slave.
That was basically the beginning of slavery. See how it carried on for many years. There always had to be some type of power over others. Some light skinned people still have some racism in them against dark skinned people. Which is still pretty sad that others that still have racism in them, because there was one man that tried to stop all that mess. But during the "Age Of Exploration" I highly doubt that nobody tried to stop Portuguese from taking dark skinned people as slaves.
