History of the Incas In some cases, these languages were taught to peoples who had originally spoken other indigenous languages. Today, Quechua and Aymara remain the most widespread Amerindian languages. The legend of the Inca has served as inspiration for resistance movements in the region. These include the 1780 rebellion led by Tupac Amaru II against the Spanish, as well as contemporary the guerrilla movements Túpac Amaru Revolutionary Movement (MRTA) and Sendero Luminoso in Peru and Tupamaros in Uruguay. History of the Incas The Incas were most notable for establishing the Inca Empire in pre-Columbian America, which was centered in what is now Peru
Machu Picchu were not perfect, as studies of the land show that there were landslides that happened during the construction of Machu Picchu. It can still be seen where the terraces were shifted by landslides and then stabilized by the Inca as they continued to build around the area. It is estimated that the area around the site has received more than 72 inches of rain per year since A.D. 1450, which was more than needed to support crop growth there. Because of the large amount of rainfall at Machu Picchu, it was found that irrigation was not needed for the terraces.
