Inca Empire Quipu

Quipu from the Tahuantinsuyo Empire (1200–1532 AD) was a sophisticated record-keeping system for the Inca civilization. Made of knotted strings, quipus encoded information through knot type, position, and color variations. They managed census data, tribute, and resources, facilitating administration across the vast empire. This tactile communication form highlights the Inca’s ingenuity in governing diverse and expansive territories.
