The Incas were a tribe of native americans who lived in the Andes Mountains. To get around, they made 19,000 miles of road and multiple suspension bridges. They lived in the Central South American culture area. They were religious people celebrating days like Capac Raymi, the celebration of young nobles turning from a child to a full grown man. Their three most important gods were: Viracocha the Creator, Inti was the Sun God, and Inti-illapa was the God of Thunder. Inca sacrificed crops and animals, mainly llamas, to ensure adequate rainfall and keep the earth fertile. Human sacrifices were made under special circumstances. Most people considered it a great honor to be chosen for sacrifice. Boys wore loose tunics that went to their knees.
