Introduction to Civil was in Inca:
From 1527 to 1532, brothers Huascar and Atahualpa fought over the Inca Empire. Their father, Inca Huayna Capac, had allowed each to rule a part of the Empire as regent during his reign: Huascar in Cuzco and Atahualpa in Quito. When Huayna Capac and his heir apparent, Ninan Cuyuchi, died in 1527 (some sources say as early as 1525), Atahualpa and Huascar went to war over who would succeed their father.
What neither man knew was that a far greater threat to the Empire was approaching: ruthless Spanish conquistadors led by Francisco Pizarro.
Background of Inca Civil War:
The Inca Emperors were considered to be divine, directly descended from the Sun. Their warlike culture had spread out from the Lake Titicaca area quickly, conquering one tribe and ethnic group after another to build a mighty Empire that spanned from Chile to southern Colombia and included vast swaths of present-day Peru, Ecuador and Bolivia.
Because the Royal Inca line was supposedly directly descended from the sun, it was unseemly for the Inca Emperors to "marry" anyone but their own sisters. Numerous concubines, however, were allowed and the royal Incas tended to have many sons. In terms of succession, any son of an Inca Emperor would do: he did not have to be born to an Inca and his sister, nor did he have to be eldest.
Often, brutal civil wars would break out upon the death of an Emperor as his sons fought for his throne: this produced much chaos but did result in a long line of strong, fierce, ruthless Inca lords that made the Empire strong and formidable. This is exactly what happened in 1527. With the powerful Huayna Capac gone, Atahualpa and Huascar apparently tried to rule jointly for a time, but were unable to do so and hostilities soon broke out.
The War of the Brothers:
Huáscar ruled Cuzco, capital of the Inca Empire. He therefore commanded the loyalty of most of the people. Atahualpa, however, had the loyalty of the large Inca professional army and three outstanding generals: Chalcuchima, Quisquis and Ruminahui. The large army had been in the north near Quito subjugating smaller tribes into the Empire when the war broke out.
At first, Huascar made an attempt at capturing Quito, but the mighty army under Quisquis pushed him back. Atahualpa sent Chalcuchima and Quisquis after Cuzco and left Ruminahui in Quito. The Canari people, who inhabited the region of modern-day Cuenca to the south of Quito, allied with Huáscar. As Atahualpa's forces moved south, they punished the Canari severely, devastating their lands and massacring many of the people.
This act of vengeance would come back to haunt the Inca people later, as the Canari would ally with conquistador Sebastian de Benalcazar when he marched on Quito.
Death of Huascar:
In November of 1532, Atahualpa was in the city of Cajamarca celebrating his victory over Huascar when a group of 170 bedraggled foreigners arrived at the city: Spanish conquistadors under Francisco Pizarro. Atahualpa agreed to meet with the Spanish but his men were ambushed in the Cajamarca town square and Atahualpa was captured.
This was the beginning of the end of the Inca Empire: with the Emperor in their power, no one dared attack the Spanish.Atahualpa soon realized that the Spanish wanted gold and silver and arranged for a kingly ransom to be paid. Meanwhile, he was allowed to run his Empire from captivity. One of his first orders was the execution of Huascar, who was butchered by his captors at Andamarca, not far from Cajamarca.
He ordered the execution when he was told by the Spanish that they wanted to see Huascar. Fearing that his brother would make some sort of deal with the Spanish, Atahualpa ordered his death. Meanwhile, in Cuzco, Quisquis was executing all of the members of Huascar's family and any nobles who had supported him.
Death of Atahualpa:
Atahualpa had promised to fill a large room half full with gold and twice over with silver in order to secure his release, and in late 1532, messengers spread out to the far corners of the Empire to order his subjects to send gold and silver. As precious works of art poured into Cajamarca, they were melted down and sent to Spain.
In July of 1533 Pizarro and his men began hearing rumors that the mighty army of Ruminahui, still back in Quito, had mobilized and was approaching with the goal of liberating Atahualpa. They panicked and executed Atahualpa on July 26, accusing him of "treachery." The rumors later proved to be false: Ruminahui was still in Quito.
Legacy of the Civil War in Inca:
There is no doubt that the civil war was one of the most crucial factors of the Spanish conquest of the Andes. The Inca Empire was a mighty one, featuring powerful armies, skilled generals, a strong economy and hard-working population.
Had Huayna Capac still been in charge, the Spanish would have had a tough time of it. As it was, the Spanish were able to skillfully use the conflict to their advantage. After the death of Atahualpa, the Spanish were able to claim the title of "avengers" of ill-fated Huáscar and March into Cuzco as liberators.
