Viewpoint of bartolome la casas and hi opinions that affected europe

Spanish colonies in the New World were cruel--Las Casas wrote many accounts of the brutality he witnessed in the New World and reported back to the Spanish government. 

Las Casas believed the encomienda system (slave labor system used by the Spanish with Native Americans) was cruel and encouraged the Spanish to end the system. Through his accounts and conversations with the government, Las Casas was able to convince the Spanish government to create regulations and laws for the system. 

Ifeel like this is a very good quesyion
