Which of these best describes the conquistadors

Conquistadors set local clans against one another, favoring their partners, as long as they were helpful. Once the victory was finished, the Native Americans were liable to abuse and subjection.  

Explanation:

Spain and Portugal marked the Treaty of Tordisillas, which was intended to separate the globe in two ranges of authority, so the two realms would not meddle with one another's investigations and victories. West of the line would be Spain's range of prominence and east would be Portugal's. The line went through what is today South America and especially Brazil. The outcome was that the vast majority of South and Central America fell under the control of Spain. Portugal colonized Brazil, which they found in 1500 and lies east of the line.  In the mid sixteenth century, the Spanish started their success of the Americas. To the extent they went, they oppressed nearby populaces and forced Christianity upon them.
