Note 20 — Chapter III · CUZCO AND THE LAND OF THE INCAS
Reading edition
The name "Inca" properly belongs to the ruling family or clan in the Peruvian monarchy, of whose ethnic relations to its subjects we know very little, but I use it here to denote not only the dynasty, but the epoch of their rule, which apparently covered two centuries (possibly more) before the arrival of Pizarro. The expression "The Inca" means the reigning monarch.
