How it all started
Faced with the need to exchange goods and products, the Qhapaq Ñan began as a herdsman road that connected the different indigenous communities of each area. With the arise of Cusco as the new administrative and political center of the communities, the Inca Empire began a process of expanding its power and territory based on the exchange of provisions which were made through this route.
Some historical background
This road were once used by the Incas for territorial expansion, maintaining a certain autonomy of each community they conquered; thus, those who were leaders would be called Carangas, and now they were the chiefs of each community. They were in charge of paying taxes to gain access to the road and holders of certain privileges.
The Incas chose their best Cusco architects to expand this herdsmen road, recognizing the land and obtaining the best materials, thus allowing the origin of the Qhapaq Ñan.
To explain it better
The different communities all over Los Andes began to eat and grow fruits, vegetables and legumes.
Finally, in the 38th World Heritage Committee, held in 2014, UNESCO decided to include Qhapaq Ñan on the World Heritage List.
