How was the Inca empire divided?

The Inca Empire was divided into four regions known as suyus, each with its own administrative, religious, and military organization. The north was named Chinchay Suyu, while the south was named Collasuyu. The east was named Antisuyu, and the west was named Contisuyu. Within each region were smaller provinces ruled by local governors who often had to deal with civil unrest. The Inca ruler appointed sub-rulers in each region who reported directly to him. The provinces were further divided into districts, and each district was broken down into individual communities or ayllu.
