The Incas lived in an mountain range.It was very hard for them to grow crops because there was land slides. It was also hard to get place to place so they built rope bridges, and terraces on the mountain.
The Incas would take children to sacrifice. The Incan high priests took the children to high mountaintops for sacrifice. These children were also physically perfect and healthy, because they were the best the people could present to their gods. The victims may be as young as 6 and as old as 15.
The Incas got conquered in 1532. The Spanish explorer Francisco Pizarro invaded the Incas. Many people got diseases and died.
