Did Inca had system of writing?

The Inca civilization did not have a system of writing in the traditional sense. Instead, they used a complex system of knotted strings known as quipu for record-keeping and communication. Quipus allowed them to manage information such as census data, tribute records, and historical events, relying on color, knot type, and placement to convey meaning. This method served their administrative needs effectively, despite the absence of a written language.
