Reign

As ruler, Pachacuti married Mama Anawarkhi, of the ayllus of Choqo and Cachona, most likely to reward a chief belonging to one of these ayllus who had defended Cusco during the Chanka invasion, and left his original family-clan (panaka) to form the imperial lineage of Hatun Ayllu, failing in his attempt to fuse the two factions. To record the history of the previous Inca rulers of Cusco, Pachacuti ordered the creation of painted wooden panels, which, in relation to oral texts, often in the form of mnemonic songs sung at important celebrations, and quipus, which contained simple and stereotyped information according to colour, order and number, decipherable by Quipucamayocs, represented official and state-sanctioned pre-imperial history.

Despite Pachacuti's prestige following the victory over the Chankas, he had "little effective power and a meager work force to undertake the development of Cusco". Instituting the system of reciprocity (a socio-economic principle regulating relations, based on obligatory and institutional mutual, "give and take", assistance) to assert his authority, Pachacuti summoned the surrounding kurakas (chiefs) to Cusco, and prepared "lavish feasts and ceremonies", tactically displaying much generosity and sharing gifts, including the booty of the war against the Chankas, before articulating gradually growing demands such as the construction of warehouses, the stocking of produce, the creation of an army, and the improvement of infrastructure. Using the means of reciprocity, Pachacuti rebuilt much of Cusco, designing it to serve the needs of an imperial city and as a representation of the empire. Each suyu had a sector of the city, centering on the road leading to that province; nobles and immigrants lived in the sector corresponding to their origin. Each sector was further divided into areas for the hanan (upper) and hurin (lower) moieties. Many of the most renowned monuments around Cusco, such as the great sun temple Qurikancha (previously Intikancha), were rebuilt during Pachacuti's reign.

At the beginning of Pachacuti's reign, the cult of the Andean creator deity Viracocha, whose priests had supported the previous ruler Viracocha Inca, was possibly replaced by the Inti Sun cult. The first months of his reign were spent putting down revolts by surrounding chiefs in the Cusco valley and consolidating the territorial base of the polity, confronting the Ayarmacas, the Ollantaytambo, the Huacara, and the Toguaro. Pachacuti conquered lands along the Urubamba valley, where he founded the famous site of Machu Picchu.
