The Huari began to decline around 1000 B.C.

There is much mystery as to how and why the large Wari Empire disappeared.

There is evidence suggesting that the empire failed at a site called Kuelap which was situated in a remote location with an enormous wall speculated to be built of three times more material than Egypt's largest pyramid.

This site was built by a people known as the Chachapoyan Cloud People who were said to be a tall people with very fair hair.
There is no evidence suggesting where these people came from.

After the steady decline of the Wari people, the Incas had begun their conquest defeating the Wari.

However, the Wari king convinced his people that the upper class Wari people were just like the Incas, too good to be under Inca rule.

This caused the Wari to flee to the lower jungles of the Andes.
