The Incas conquered a number of neighboring peoples as they expanded
their area of influence outward from their home in the Cuzco valley
of highland Peru
. Inca lands eventually totaled about 906,500 sq km (about 350,000
sq mi). This territory centered on the peaks of the Andes, but extended
to the Pacific Coast and the Amazon basin. The political center
of the empire was in what is now Peru, and its territory included
parts of present-day Ecuador, Bolivia, northern Chile, and northwest
Argentina. The terrain included high grass plateaus, low-lying jungles,
deserts, and fertile river valleys. II
