Andean civilizations, Inca Empire and Global Warming

Spanish rule ended or transformed many elements of the Andean civilizations notably influencing religion and architecture.

Today climate change is melting glaciers that allowed the Incan canal system to work, threatening current water supplies throughout the Andes.

Inca Empire was the largest empire in pre-Columbian America. The administrative, political and military center of the empire was located in Cusco in modern-day Peru. The Inca civilization arose from the highlands of Peru sometime in the early 13th century.

Inca expansion (1438–1533)

Andean civilization probably began c. 9500 BP. Based in the highlands of Peru, an area now referred to as the punas, the ancestors of the Incas probably began as a nomadic herding people. Geographical conditions resulted in a distinctive physical development characterized by a small stature and stocky build. Men averaged 1.57 m (5'2") and women averaged 1.45 m (4'9"). Because of the high altitudes, they had unique lung developments with almost one third greater capacity than other humans. The Incas had slower heart rates, blood volume of about 2 l (four pints) more than other humans, and double the amount of hemoglobin which transfers oxygen from the lungs to the rest of the body.

Archaeologists have found traces of permanent habitation as high as 5,300 m (17,400 ft) above sea level in the temperate zone of the high altiplanos. While the Conquistadors may have been a little taller, the Inca surely had the advantage of coping with the extraordinary altitude. It seems that civilizations in this area before the Inca have left no written record, and therefore the Inca seem to appear from nowhere, but the Inca were a product of the past. They borrowed architecture, ceramics, and their empire-state government from previous cultures.

In the Lake Titikaka region, Tiwanaku is recognized by Andean scholars as one of the most important precursors to the Inca Empire, flourishing as the ritual and administrative capital of a major state power for approximately 500 years.

Sacsayhuamán, the Inca stronghold of Cusco

 The Spanish installed Atahualpa's brother Manco Inca Yupanqui in power; for some time Manco cooperated with the Spanish, while the Spanish fought to put down resistance in the north. Meanwhile an associate of Pizarro's, Diego de Almagro, attempted to claim Cusco for himself. Manco tried to use this intra-Spanish feud to his advantage, recapturing Cusco in 1536, but the Spanish retook the city afterwards. Manco Inca then retreated to the mountains of Vilcabamba, Peru, where he and his successors ruled for another 36 years, sometimes raiding the Spanish or inciting revolts against them. In 1572 the last Inca stronghold was conquered, and the last ruler, Túpac Amaru, Manco's son, was captured and executed. This ended resistance to the Spanish conquest under the political authority of the Inca state.

 After the fall of the Inca Empire many aspects of Inca culture were systematically destroyed, including their sophisticated farming system, known as the vertical archipelago model of agriculture. Spanish colonial officials used the Inca mita corvée labor system for colonial aims, sometimes brutally. One member of each family was forced to work in the gold and silver mines, the foremost of which was the titanic silver mine at Potosí. When a family member died, which would usually happen within a year or two, the family would be required to send a replacement.

The effects of smallpox on the Inca empire were even more devastating. Beginning in Colombia, smallpox spread rapidly before the Spanish invaders first arrived in the empire. The spread was probably aided by the efficient Inca road system. Within a few years smallpox claimed between 60% and 94% of the Inca population, with other waves of European disease weakening them further. Smallpox was only the first epidemic. Typhus (probably) in 1546, influenza and smallpox together in 1558, smallpox again in 1589, diphtheria in 1614, measles in 1618 – all ravaged the remains of Inca culture.

Modern flag of the city of Cuzco.

In modern times the rainbow flag has been associated with the Tawantinsuyu and is displayed as a symbol of Inca heritage in Peru and Bolivia. The city of Cusco flies the Rainbow Flag. Even the Peruvian president Alejandro Toledo (2001–2006) flew the Rainbow Flag in Lima's presidential palace.

According to the Peruvian newspaper El Comercio, the flag only dates to the first decades of the 20th century. But in his 1847 book A History of the Conquest of Peru, "William H. Prescott ... says that in the Inca army each company had its particular banner, and that the imperial standard, high above all, displayed the glittering device of the rainbow, the armorial ensign of the Incas." A 1917 world flags book says the Incan "heir-apparent ... was entitled to display the royal standard of the rainbow in his military campaigns."

Incan empire aided by global warming:The warmer temperatures allowed the Inca to irrigate agricultural terraces fed by canals bringing glacial melt-water to the fields. Additionally, the Inca planted trees on the hillsides to prevent erosion and increase soil fertility.

This all led to a surplus of food (maize and potatoes primarily), which in turn enabled the Inca to expand their empire, building an extensive road network and the grand structures by which they are remembered today.

  

Also, the warming which allowed the Inca to thrive was of a different scale entirely than that which is predicted and occurring today. It followed an extended period of drought -- which likely brought down the previous Wari empire -- and ultimately made the region more habitable.

Today climate change is melting glaciers that allowed the Incan canal system to work, threatening current water supplies throughout the Andes. Throughout most of the world climate change will move the climate towards being less hospitable not more.
