What were the main attributes of inca culture?

We could name many attributes of the Inca culture, the most important were:

The empire of the Incas was from the political point of view, an absolutist and theocratic monarchy. The power was centralized in the Inca who was considered of divine origin. The right to govern was inherited. The great element of unification was the language, all conquered peoples had to learn and practice Quechua or Runa Simi because it was the official language of Tahuantinsuyo, for this the Incas sent teachers who taught and monitored the practice of Quechua. There were great differences between social classes, these differences being respected by all the inhabitants of the Empire. The hierarchical classes formed a pyramid where the Inca, with all the power, was on the cusp, while the town, which was the vast majority, constituted its social base. With great skill and dexterity, the Inca architecture handled the geometric design in a thousand wonders, building eternal constructions full of life, with a respect for nature, and incredibly aligned at sunrise at certain times of the year. All this success corresponded to a previous architectural planning with sketches, plans or models, as well as the use of a measurement system related to the human body.
