Inca Empire History Quiz

Open after playing to review every question, the correct answers, and the historical explanations.

1. What was the Inca name for their empire?

   Tawantinsuyu

   The Incas called their empire Tawantinsuyu, meaning "The Four Regions Together" in Quechua. The empire was divided into four suyus (quarters) radiating from the capital Cusco: Chinchaysuyu (north), Antisuyu (east), Collasuyu (south), and Cuntisuyu (west).

2. Which Inca ruler is credited with transforming the Inca from a small kingdom into a vast empire in the 15th century?

   Pachacuti

   Pachacuti (reigned c. 1438–1471) is considered the founder of the Inca Empire as a major power. After defending Cusco against the Chanka invasion, he launched a series of conquests and reorganized the state, implementing the administrative systems that made the empire function.

   Fun Fact: Pachacuti is also credited with building Machu Picchu as a royal estate.

3. What was a quipu and what was it used for?

   A system of knotted strings used for record-keeping

   Quipus were recording devices made of cotton or camelid fiber strings with knots tied at various positions. The knots encoded numerical data used for census records, tax obligations, and inventories. The Incas had no written script, making quipus their primary method of information storage.

   Fun Fact: Around 600 quipus survive today, and scholars are still working to fully decode them. Some researchers believe quipus may have recorded narrative information, not just numbers.

4. Approximately how long was the Inca road system (Qhapaq Nan) at its peak?

   About 30,000 km

   The Qhapaq Nan, or Great Inca Road, stretched approximately 30,000 km (about 18,600 miles) across diverse terrain including coastal deserts, Andean peaks, and tropical forests. It connected the far reaches of the empire and facilitated rapid communication through a relay runner (chasqui) system.

5. What was the mit'a system in the Inca Empire?

   A form of mandatory labor service owed to the state

   The mit'a was a mandatory public service system in which every adult member of the empire owed a certain amount of labor to the state each year. This labor was used for building roads, terraces, temples, and military service. In return, the state provided food, chicha (corn beer), and coca leaves to workers.

6. What material did the Incas use to build their most important structures?

   Precisely cut and fitted stone blocks without mortar

   The Incas were master stonemasons who cut massive stone blocks so precisely that they fit together without mortar, a technique called ashlar masonry. The joints are so tight that not even a knife blade can be inserted between the stones. This technique also made their buildings remarkably earthquake-resistant.

7. What was the capital of the Inca Empire?

   Cusco

   Cusco, located at about 3,400 meters (11,200 feet) above sea level in the Peruvian Andes, was the political, religious, and administrative capital of the Inca Empire. The Incas considered it the "navel of the world." The city was laid out in the shape of a puma, with the fortress of Sacsayhuaman forming the head.

8. What purpose did Machu Picchu most likely serve?

   It was a royal estate and sacred religious site

   Modern archaeological evidence suggests Machu Picchu was built around 1450 CE as a royal estate for Emperor Pachacuti. It served as a country retreat for Inca nobility and had important religious significance. It was never a large city; at its peak, only about 750 people lived there.

   Fun Fact: Machu Picchu was never found by the Spanish conquistadors. It was introduced to the outside world by American historian Hiram Bingham in 1911, though local farmers had known of its existence.

9. What agricultural technique did the Incas perfect to farm on steep mountain slopes?

   Stone-walled terracing (andenes)

   The Incas built extensive agricultural terraces called andenes on steep hillsides throughout the Andes. These step-like platforms prevented erosion, created microclimates at different elevations, and maximized arable land in the mountains. The terraces at Moray may have served as an agricultural experimentation station.

10. Which Spanish conquistador captured the Inca emperor Atahualpa in 1532?

    Francisco Pizarro

    Francisco Pizarro captured Atahualpa at Cajamarca on November 16, 1532, in a surprise ambush during what was supposed to be a peaceful meeting. Despite Atahualpa paying an enormous ransom of gold and silver that filled a room, Pizarro had him executed in July 1533.

11. What was the "ransom room" of Cajamarca?

    A room Atahualpa promised to fill with gold and silver for his freedom

    After his capture, Atahualpa offered to fill a room approximately 6.7 meters long by 5.2 meters wide with gold once to the height of his raised hand, and fill it twice more with silver. This enormous ransom was collected from across the empire, but Pizarro executed Atahualpa anyway.

    Fun Fact: The ransom is estimated to have been worth over $1.5 billion in today's money, making it one of the largest ransoms in history.

12. What role did chasquis play in the Inca Empire?

    They were relay runners who carried messages across the empire

    Chasquis were highly trained relay runners stationed at intervals of about 6–9 km along the Inca road system. Each runner sprinted to the next station, passing the message or package to the next runner. This system could relay a message about 240 km (150 miles) per day across the rugged Andean terrain.

13. What civil war weakened the Inca Empire just before the Spanish arrived?

    A succession war between Atahualpa and Huascar

    When Emperor Huayna Capac died around 1527, likely from a smallpox epidemic that preceded the Spanish, a devastating civil war erupted between his sons Atahualpa and Huascar over succession. Atahualpa had just won this war when Pizarro arrived, and the empire was deeply divided and weakened.

14. What was the Inca practice of "split inheritance"?

    The new emperor inherited the title but not the previous ruler's wealth or property

    Under Inca split inheritance, a new emperor received the political title and power but none of his predecessor's lands, palaces, or wealth. The previous ruler's mummy and descendants (panaca) retained all his property. This meant each new emperor had to conquer new territory to build his own wealth, driving imperial expansion.

15. Which important Inca religious festival celebrated the sun god Inti at the winter solstice?

    Inti Raymi

    Inti Raymi was the most important religious ceremony in the Inca calendar, honoring the sun god Inti at the winter solstice (June in the Southern Hemisphere). The festival lasted nine days and included feasting, music, and animal sacrifices. The Sapa Inca presided over the ceremony at Sacsayhuaman.

    Fun Fact: Inti Raymi was banned by the Spanish in 1572 but was revived in 1944. Today it is celebrated every June 24 in Cusco and attracts thousands of visitors.
