Through archeological studies carried out at other sites, it was concluded that the first settlers probably arrived from Asia around 2,000 BCE, settling in the area of Pacaicasa (Ayacucho), according to José Rios Velazquez.

[1] Before the Incan civilization had settled the area, there were various peoples that populated the region, like the Quechuas, Pocras, Aucarunas, and Aymaras.

Pedros José Rios Velazques supposes that this last version could be the closest to the truth given that, during the reign of Pachacutec, the rebels moved away towards the Andean towns that were farther from Cuzco, the capital.

According to Murra (1983) and Garcilaso (1960), the Yanas could have benefited from their minority status within the Incan social hierarchy, taking on jobs at the noble court like carpentry, cooking, water carrier, sweeper, etc.

His investigation led to the discovery that Yanaca was a city that had an important role in Incan social, political, and religious organization.

In 1720, Don Juan de Beytia, a magistrate sent by Spanish King Philip V, arrived to Yanaca and decreed that the towns should be separated and formed into independent communities.

It might have served as an observatory, and the shade of the mountains protecting the valley could have signaled the agricultural cycles, solstices, and equinoxes.

Doctor Juan Ossio Acuña, Peruvian Minister of Culture since September 2010, carried out a study in 1996 of the Yanaca people, including their traditions and their pre-Incan history.

Doctor R. Tom Zuidema carried out studies about the Inca and mentioned Yanaca, stating that the Rimacvillca group belonged to this people.
