Which of the following was a result of slave raiding by Portuguese slavers in Kongo?

A. England went to war with France

B. Portugal split apart into three separate nations

C. Relations between Kongo leaders and the Portuguese became strained

D. Portugal went to war with England

C. Relations between Kongo leaders and the Portuguese became strained.

The Kongo initially was hopeful for the new market and technological knowledge the Portuguese could share. However, when the Portuguese found that they could not supply the expected gold and copper volume, the foreigners took slavery as a much more valuable commodity for their sugar-cane plantations. King Alfonso said in his letter to the King of Portugal, "Sir, Your Highness should know how our Kingdom is being lost in so many ways ..."

The correct answer is Option C. Relations between Kongo leaders and the Portuguese became strained.

Relations between Kongo leaders and the Portugese became strained as a result of Slave Raiding by the Portuagese.

In the 'age of exploration' and more precisely the European Colonisation of Africa, every colonial power was looking to establish a large trading base.

Portugese used to raid Kongo (Congo) to capture, kidnap and enslave localpeople and then sell them off in the slave trade business. These slaves were usually sold off in the new world to work on sugar, cotton and other plantations.

The Portugese established a profitable business out of African slavery but it started to create huge friction between them and the local leaders.
