Who they are

Pachacuti (reigned c. 1418–1471/1472) was the ninth Sapa Inca (emperor) of the Inca Empire, who in his father’s reign successfully repelled the invasion of the powerful Chanka, then seized the throne and launched a series of great military expansions and administrative reforms, expanding what had been a small tribal state confined to a corner of the Cusco valley into the empire spanning the whole Andes range, the most vast in South American history. He rebuilt the city of Cusco as the religious and political center of the empire, built much mountain architecture including Machu Picchu, and organized the building of the "Inca road" system, perhaps more than thirty thousand kilometers long in total, which, together with a relay system of runners, achieved effective administration of a vast mountain territory — a level of infrastructure construction that is a marvel among the ancient American civilizations that had neither wheeled transport nor a system of writing.

Key stories

Repelling the Chanka Invasion

In Pachacuti’s youth the Inca’s old enemy the Chanka invaded the Cusco valley in force, and his father for a time abandoned the city and fled, but Pachacuti held Cusco, organized its defense, and at last repelled the Chanka assault; legend says that at the fiercest moment of battle even the stones turned into warriors to help — this defensive battle of the weak overcoming the strong laid the political capital for his later seizure of the throne and imperial expansion.

The Inca Road and the Runner System

Pachacuti organized the building of the "Inca road" system crisscrossing the Andes, estimated at more than thirty thousand kilometers in total, with relay stations along the way where runners (chasqui) ran in relay to pass information, so that even without wheeled vehicles important news could travel across the empire at astonishing speed — this infrastructure was key to the Inca Empire’s effective governance of complex mountain terrain.

Version differences

The Inca Empire left no system of writing, and the record of Pachacuti’s life comes mainly from oral history ordered by colonizers and mixed-blood descendants after the Spanish conquest, its accuracy and degree of later embellishment an ongoing topic in Andean archaeology and history.
