c. mid-15th century CE / Americas
Inca Roads Span the Andes
Inca rule centered on Cuzco expanded rapidly, with roads, storage facilities, and labor-service systems connecting mountains, coasts, and river valleys.
The story
In the fifteenth century, Pachacuti and his successors expanded and reshaped the Inca state centered on Cuzco. Rulers used existing roads and new construction projects to organize labor service, transmit information, and move supplies; knotted-cord records also served administration. The empire integrated many different communities, but conquest, relocation, and the extraction of resources were also important. Precise dates for the early dynasty depend on later accounts, so the middle of the century is used here to indicate the phase of expansion.
Elsewhere in the world
As the Inca expanded, Ming China and Indian Ocean port cities were also developing large transport networks, but the Andean system had its own historical foundations.
