What caused the fall of machu picchu?

Answer 1

The fall of Machu Picchu is attributed to several factors, primarily the Spanish conquest in the 16th century, which led to the decline of the Inca Empire. Although it is believed that the site was abandoned before the Spanish arrived, the conquest disrupted trade and agriculture in the region, contributing to its decline. Additionally, environmental factors, such as landslides and deforestation, may have also played a role in its abandonment. Ultimately, Machu Picchu was largely forgotten by the outside world until its rediscovery in the early 20th century.
