Quipus were a system of knotted strings used by the Incas to record information and manage their vast empire. They helped solve problems related to accounting, data management, and communication by allowing the Incas to keep track of resources, populations, and military information without a written language. This efficient record-keeping facilitated administrative control and helped maintain the cohesion of their expansive territory. Overall, quipus were essential for the effective governance and organization of Inca society.
