Topa Inca Yupanqui: The Inca Conqueror of Chimor and Chile

Topa Inca Yupanqui, also known as Tupac Inca Yupanqui, was the Inca ruler who turned his father Pachacuti’s highland state into a vast empire stretching along the Andes. As a general from the 1460s and as sole ruler from around 1471 until about 1493, he led campaigns that reached Ecuador in the north and central Chile in the south and brought the rich Chimu kingdom under Inca control. His reign marked the greatest territorial expansion in Inca history.

Background

Topa Inca was the son of Pachacuti, the ruler who, according to tradition, saved Cusco from the Chanka around 1438 and began the expansion of the Inca state, and of his principal wife Mama Anahuarque. As Pachacuti grew older, he gave his son command of the armies and, according to several chronicles, made him co-ruler for some years before handing over power.

All dates for this period come from Spanish chronicles written decades later, mainly those of Pedro Sarmiento de Gamboa and Miguel Cabello Valboa. The widely used dates of 1471 for Topa Inca’s sole rule and 1493 for his death were proposed by the historian John Rowe on that basis. Recent radiocarbon research suggests the early Inca chronology may need adjusting, so all such dates should be treated as approximate.

Northern campaigns

In the 1460s Topa Inca led Inca armies north through the central highlands. He conquered the kingdom of Cajamarca, defeating a Chimu force sent to support it, and then advanced into what is now Ecuador. There he fought the Cañari people of the southern highlands, who were eventually absorbed into the empire, and pushed on towards Quito. The Inca later built a major centre at Ingapirca, in Cañari territory, where an oval stone platform known as the Temple of the Sun still stands beside earlier Cañari remains.

Ecuador proved hard to hold. Its peoples were organised in many small chiefdoms that resisted fiercely, and campaigns there continued under Topa Inca’s son. The Inca built forts, roads and administrative centres to secure the region, and Tumebamba, near modern Cuenca, grew into a northern royal seat.

The most important victory of these years was the conquest of Chimor, the Chimu kingdom on Peru’s north coast, around 1470. Its ruler Minchancaman was taken to Cusco, and its treasures and skilled metalworkers were brought to the Inca capital. With Chimor gone, no other state in the Andes could match the Inca.

Sarmiento de Gamboa also records that Topa Inca sailed from the Ecuadorian coast with a fleet of rafts to two distant islands, returning with captives and exotic goods. The story has inspired speculation about a voyage to Polynesia, but historians treat it as an uncertain tradition with no firm evidence.

Southern campaigns and Chile

After becoming sole ruler, Topa Inca turned south. He first had to put down a large revolt among the peoples of the Lake Titicaca region, the Colla and Lupaca, who rose up when he was campaigning in the eastern lowlands. The revolt was crushed and Inca control over the altiplano reinforced.

He then led or sent expeditions far to the south. Inca armies occupied large parts of what are now Bolivia and north-western Argentina and moved down into Chile. According to the chronicles, the Inca advance in Chile was halted around the Maule River, where local peoples resisted fiercely. The Maule area is usually regarded as the southern limit of the empire.

Campaigns into the Amazonian forests east of Cusco, known as the Antisuyu, were less successful. The terrain, climate and scattered peoples of the lowlands made conquest difficult, and Inca control there remained limited.

How the Inca army conquered

Inca expansion relied as much on diplomacy and logistics as on battle. Before attacking, Inca commanders usually offered local rulers the chance to submit peacefully. Those who accepted kept their positions, received gifts of fine cloth and other goods, and sent their sons to Cusco to be educated, where they also served as hostages.

Those who refused faced large armies made up of soldiers drawn from conquered peoples through labour service. These armies could be supplied over long distances because of the network of state storehouses, called qollqa, filled with food, cloth and weapons. Speed and numbers often overwhelmed enemies before they could unite, and harsh punishments for rebellion discouraged further resistance.

Administration and reforms

Topa Inca’s reign was not only one of conquest. Many of the institutions that held the empire together were developed or expanded under him. Conquered regions were organised into provinces, and the population was counted in units of 10, 100, 1,000 and 10,000 households for the purposes of labour service and administration.

The empire relied on the mit’a, a system of rotating labour service, rather than taxes in money or goods. Communities worked state and religious lands, served in the army and built roads, storehouses and temples. Records were kept on khipu, knotted cords that recorded numbers and probably other information.

Topa Inca also made heavy use of mitma, the resettlement of whole communities. Loyal groups were moved into newly conquered regions, and rebellious peoples were scattered to distant provinces. The Inca road system, the Qhapaq Ñan, was extended to connect the new territories, with storehouses and way stations along the routes.

Key people

• Topa Inca Yupanqui: Inca ruler c. 1471–1493 and the main commander of Inca expansion.
• Pachacuti: his father, founder of the imperial state and his predecessor.
• Mama Ocllo: his principal wife (coya) and sister, mother of his successor.
• Minchancaman: the last independent ruler of Chimor, defeated by Topa Inca’s armies.
• Huayna Capac: his son and successor from about 1493, the last ruler of a united empire.

Death and succession

Topa Inca Yupanqui died around 1493. The chronicles disagree about the circumstances, and some mention rumours of poisoning connected with rivalries over the succession. After a short dispute, his son Huayna Capac took power and continued campaigns in Ecuador.

Like other Inca rulers, Topa Inca was mummified after death and his body was cared for by his royal lineage, which kept his estates and property. According to colonial accounts, his mummy was burned during the conflicts that followed the death of Huayna Capac.

Legacy

Topa Inca Yupanqui ruled over the largest empire in the pre-Columbian Americas, whose population at its height is often estimated at about 10 million people, with scholarly figures ranging from roughly 6 to 14 million. Most of its borders, from Ecuador to central Chile, were set during his campaigns.

His name lived on long after the empire’s fall. The 18th-century rebel José Gabriel Condorcanqui took the name Túpac Amaru II, recalling earlier Inca rulers, and the Tupac name became a symbol of indigenous identity in Peru and beyond.

• c. 1470: Conquest of Chimor on Peru’s north coast.
• c. 1471: Topa Inca becomes sole ruler after Pachacuti steps down.
• 1470s–1480s: Revolt in the Titicaca region is suppressed; expansion into Bolivia, Argentina and Chile.

• c. 1493: Death of Topa Inca Yupanqui; Huayna Capac succeeds him.

Why it matters

Topa Inca Yupanqui’s campaigns created the Inca Empire in the form the Spanish encountered in 1532. His conquests and administrative systems tied together a huge, diverse territory along the Andes, making Tawantinsuyu one of the great empires of the 15th-century world.
