In the beginning, when the Incas were establishing their power base around Cuzco, they formed alliances with a wide variety of different ethnic groups through the practice of intermarriage. The Inca ruler would marry the daughter of a local ethnic leader, and then the Inca ruler would give one of his daughters in reciprocal marriage to that local ethnic leader.
The military prowess of Viracocha Inca’s two uncles helped him to achieve victory over the Ayarmaca empire, which was located to the south, and to seize control of the Urubamba Valley. In addition to this, he is credited with instituting the Inca custom of establishing military garrisons in newly acquired territories in order to ensure continued peace.
The once-mighty Inca Empire, which ruled much of what is now known as South America, is largely a thing of the past. After a very small army of Spanish conquistadors successfully invaded the continent in the 16th century, an abrupt end came to pass for the once-powerful and influential Inca civilisation. This was due to the fact that the Incas had been conquered by the Spanish.
When the Spanish arrived in the Americas, the empire of the Incas, which had its origins in the Andes mountains, was the greatest one there. Archaeologists estimate that it took the Incas around two hundred years to build their nation into an empire. It is likely that the Incas were engaged in three or four different activities at the same time.
The Inca were able to maintain control of their huge empire because to its efficient road network, which made communication, commerce, and defense easier to carry out throughout the empire’s many different areas. There are several additional relics left behind by the Inca that are evidence of the splendor of their culture. Some of these relics are more well-known than others.
When they were at the pinnacle of their power in the early 1500s C.E., the Incas reigned over a huge empire that was exceptionally well-organized. The Inca Empire covered practically the entire length of the Andes mountain range, which is equivalent to roughly 2,500 miles when measured in a north-to-south direction.
