All of this labor and planning was directed by architects and master stone masons under the Inca king's supervision. These workers were highly skilled in their occupations. They built fortresses, temples, and palaces for the king all over the empire(Cobo 227).
The work of unskilled workers was of great importance also. There was a lot of work that went into building each structure. A large number of unskilled workers were needed to help quarry rocks, move them, and raise them into position(Malpass 58).
Almost all structures that are considered to be Inca today were probably built after the year 1440 A.D(Rostworowski de Diez Canseco 48). The Inca used an abundant state workforce based on a system of rotational labor to supply their workers(Rostworowski de Diez Canseco 48).
had a similar labor system to the Incas in a sense. Their priest
king would supervise the work, specialized workers such as architects worked
on the design, and a large group of unskilled laborers did the pain saking
work. For more information on this see Mayan Labor.
