Because of its location strategically established for its protection, because of its number of temples and their architectonic quality, because of the small amount of "kanchas" (apartments for extended families), and because of the several characteristics that Machupicchu presents: originally, it was a regional power center dependent from Qosqo. That is, it was a small religious and political capital. Surely, it served as a dwelling for the Inka or any high ranked dignitary from the Capital, as well as for a selected nobility that had the privilege of having an "Aqllawasi" that was something like a monastery for "Chosen Women" or "Virgins of the Sun" devoted to cult and for service of its privileged population too. Most modern archaeologists and historians state that Machupicchu was made built and used by Inka Pachakuteq, who was the Tawantinsuyo's greatest statesman and ruled from 1438 to 1471, as his "Royal Farmstead". Scholars use for this assertion the chronological dating given by the carbon 14 or radiocarbon, its doubtless "Imperial Inka" architectonic style, the predominant ceramic pieces, and some other scientifically valid facts. Even more, the archaeological evidences discard totally any possibility of pre-Inkan settlements in this region. According to the buildings that are found in the Inkan City, the population during its apogee is calculated to have been about 1000 people. According to the mummies found by the Bingham expedition about 80% of the Machupicchu population were women; that is the strong support to assert that over here existed an important "Aqllawasi" (House of Chosen Women), chosen among the prettiest and most virtuous, they were considered as the Sun's wives. Many modern scholars suggest that a large part of them were the Inka's wives too, considering that he was the son of the Sun; therefore, a living god. Thus the Inka lived in his property, along with his wives. It was normal for the Inka to have hundreds of concubines, and for example, our history states that Wayna Qhapaq who was father of Waskar and Atawallpa had more than 400 children. Nevertheless, his main wife must have been a sister of his; only that way they could keep the "solar blood" that they supposedly had. The throne heir had to be a son of the Inka and his sister.
