How did they treat the Inca empre?

The Spanish conquistadors treated the Inca Empire with extreme violence and brutality. After their arrival in the early 16th century, they exploited internal divisions and captured the Inca ruler Atahualpa, demanding a ransom in gold. Once the ransom was paid, the Spanish executed Atahualpa and launched a campaign of conquest, plundering Inca cities and decimating the population through warfare and introduced diseases. This led to the collapse of the Inca Empire and significant suffering for its people.
