USA HISTORY

Detailed explanation-1: -The Inca Empire (1438–1533) had its own spoken language, Quechua, which is still spoken by about a third of the Peruvian population. It is believed that the only “written” language of the Inca empire is a system of different knots tied in ropes attached to a longer cord. This system is called quipu or khipu.

Detailed explanation-2: -The Incas never developed a written language. However, their system of record keeping called Quipu is unique in human history. Inca recorded accounts with knotted string. Quipu means knot in Quechua, the language of the Incas.

Detailed explanation-3: -The Incas may not have bequeathed any written records, but they did have colourful knotted cords. Each of these devices was called a khipu (pronounced key-poo). We know these intricate cords to be an abacus-like system for recording numbers.

Detailed explanation-4: -The Inca, a technologically sophisticated culture that assembled the largest empire in the Western Hemisphere, have long been considered the only major Bronze Age civilization that failed to develop a system of writing-a puzzling shortcoming that nowadays is called the “Inca Paradox.”

Detailed explanation-5: -Much like the Romans, the Inca demanded their subjects worship the Emperor and acknowledge the primacy of their gods. Much like the Romans they had an incredible network of roads. But they’re also famous for one other thing: They didn’t have the wheel.
