Inca civilization - Arts and technology

Arts and technology

Monumental architecture

Inca architecture was by far the most important of the Inca arts, with pottery and textiles reflecting motifs that were at their height in architecture. The main example is the capital city of Cuzco. The site of Machu Picchu was constructed by Inca engineers. The Inca constructed stone temples without using mortars yet the stones fit together so well that one could not fit a knife through the stonework.
The rocks used in construction were sculpted to fit together exactly by repeatedly lowering a rock onto another and carving away any sections on the lower rock where the dust was compressed. The tight fit and the concavity on the lower rocks made them extraordinarily stable. In areas with fewer stone resources, buildings were constructed using materials such as mud-brick adobe, which would then be covered in stucco and painted for additional durability. At the late Inca settlement of Tambo Colorado, for example, color was often applied in horizontal strips of red, black, white, and yellow ochre atop stucco, and variation in color would accentuate architectural features such as niches.
The Inca had an extensive road system which consisted of two main roads as described in the following quote by Cieza de Léon: "The Incas built two roads the length of the country. The Royal Road went through the highlands for a distance of 3,250 miles, while the Coastal Road followed the seacoast for 2,520 miles."
Ceramics, precious metal work, and textiles

Almost all of the gold and silver work of the empire was melted down by the conquistadors. Ceramics were painted in numerous motifs including birds, waves, felines, and geometric patterns. The most distinctive Inca ceramic objects are the Cusco bottles or ¨aryballos¨. Many of these pieces are on display in Lima in the Larco Archaeological Museum and the National Museum of Archaeology, Anthropology and History. Textiles were important in that they showed social status, and could also be used as armor. Another important use of textiles was in the creation of rope bridges across gorges.
Agriculture and farming

The Inca lived in mountainous terrain, which is not good for farming. To resolve this problem, terraces were cut into steep slopes, known as andenes, in order to plant crops. They also used irrigation. They grew maize, quinoa, squash, tomatoes, peanuts, chili peppers, melons, cotton, and potatoes. Though all of their agriculture was important, their main food source was potatoes, unlike the Maya and the Aztecs, whose main food source was maize. The Inca was the first civilization to plant and harvest potatoes. Quinoa was also a main crop. They would use their seeds to make different foods.
The Inca were the first civilization to use the freeze-dry method of storage. They would leave potatoes outside in the cold, then stomp on them in the morning to push out the water, and allow them to dry in the sun. This process would be repeated 3 or 4 times, until the dried potatoes were ready for storage. At this point they were called chuño.
Discoveries
Mathematics and medicine
An important Inca technology was the Quipu, which were assemblages of knotted strings used to record information, the exact nature of which is no longer known. Originally it was thought that Quipu were used only as mnemonic devices or to record numerical data.
The Incas had no iron or steel, but they had developed an alloy of bronze superior to that of their enemies and contemporary Mesoamericans. The Andean nations prior to the Incas used arsenical bronze at best. The Incas introduced to South America the tin / copper alloy which is today commonly associated with "Bronze Age" metallurgy.

history of Peru- Inca civilization

The first step in the expansion of the Inca Empire was the defeat of the Hanan Chankas, a group that lived in the departments of Ayacucho and Huancavelica, near Cuzco. That allowed them to control a large territory around Cuzco and incorporate its population into its army. The expansion continued to the Lake Titicaca region where they allied with the Lupaca ethnic group to defeat the powerful Hatun Colla. The Incas had a special interest to control this region due to their abundant natural resources. After his military victory, Inca Pachacuti rebuilt Cuzco.

In 1438 AD, under the command of Sapa Inca (paramount leader) Pachacuti, much of modern day southern Peru was conquered. Cuzco was rebuilt as a major city and capital of the newly reorganized empire. Known as Tawantinsuyu, it was a federalist system, consisting of a central government with the Inca at its head and four provincial governments with strong leaders: Chinchasuyu (NW), Antisuyu (NE), Contisuyu (SW), and Collasuyu (SE). The powerful Inca emperor is also thought to have built Machu Picchu, either as a family home or as a vacation retreat.

The Incas conquered a vast territory using reciprocity or alliances. Pachacuti would send spies to regions he had wanted in his empire. They would then report back on the political organization, military might, and wealth. The Sapa Inca would then send messages to the leaders of these lands, extolling the benefits of joining his empire. He offered gifts of luxury goods like high quality textiles,coca leaves and mullu and promised that all living in those territories would be materially richer as subject rulers of the Inca. Most accepted the rule of the Inca as a fait accompli and acquiesced peacefully. The neighboring rulers' children would be brought to Cuzco to be taught about Inca administration systems, and then would return to rule their native lands. This allowed the Inca to indoctrinate the former rulers' children into the Inca nobility, and, with luck, marry their daughters into families at various corners of the empire. If they did not accept the alliance they used force to subdue the tribe and since the Incas had a more powerful military force they always succeeded. The local leaders were executed to secure loyalty among the population.

Inca civilization - history of Peru

The Inca civilization (or Inka) began as a tribe in the Cuzco area, where the legendary first Sapa Inca, Manco Capac founded the Kingdom of Cuzco around 1200. Under the leadership of the descendants of Manco Capac, the Inca state grew to absorb other Andean communities. In 1442, the Incas began a far-reaching expansion under the command of Pachacutec. He founded the Inca Empire or Tahuantinsuyo, which became the largest empire in pre-Columbian America.

The empire was split by a civil war to decide who would be Inca Hanan and who would be Inca Hurin (Hanan and Hurin represent the families of the higher parts of the city (Hanan) and those of the lower parts (Hurin) it is believed that one of the brothers was from Hanan Cuzco and the other from Hurin Cuzco as they were part of the family of their mothers), which pitted the brothers Huascar and Atahualpa against each other. In 1533, Spanish Conquistadores led by Francisco Pizarro, took advantage of this situation and conquered much of the existing Inca territory. In succeeding years, the invaders consolidated power over the whole Andean region, repressing successive Inca resistance and culminating in the establishment of the Viceroyalty of Perú in 1542.

The militant phase of Inca liberation movements ended with the fall of resistance in Vilcabamba during 1573. Though indigenous sovereignty was lost, Inca cultural traditions remain strong among surviving indigenous descendants, such as the Quechua and Aymara people.

 History of the Incas
According to myth, Incan civilization began with Manco Capac, who carried a golden staff called the ‘tapac-yauri’. The Inca were instructed to create a Temple of the Sun in the spot where the staff sank into the earth, to honor their celestial father. After a long journey, including a tour of the underworld, the Inca arrived at Cuzco, where they built the temple. During the journey, one of Manco’s brothers, and possibly a sister, was turned to stone (huaca) = "sacred/holy". 

In another version of this legend, instead of emerging from a cave in Cuzco, the siblings emerged from the waters of Lake Titicaca.
In ancient times Inca Virachocha's son Manco Cápac lived at Pacari-Tampu, today known as Pacaritambo, 25 km (16 mi) south of Cuzco. He and his brothers (Ayar Anca, Ayar Cachi, and Ayar Uchu), and sisters (Mama Ocllo, Mama Huaco, Mama Raua, and Mama Cura) lived near Cuzco at Paccari-Tampu. Uniting their people, and the ten ayllu they encountered in their travels, they set to conquering the tribes of the Cuzco Valley. This legend also incorporates the motif of the golden staff, given to Manco Capac by his father. Accounts vary, but according to some versions, the young Manco jealously betrayed his older brothers, viciously raped and killed them, and thus became the sole ruler of Cuzco.
