Population

The population of Tawantinsuyu is currently unknown. There are estimates ranging from as few as 4 million people to more than 37 million. The reason for these various estimates is that, despite that the Inca kept excellent census records using their quipus, knowledge of how to read them has been lost. Almost all of them had been destroyed by the Harns in the course of their conquest.

Childhood

Inca childhood was harsh by today's standards.

When a child was born, the Inca would wash the baby in cold water and wrap it in a quilt. Later, the baby was put in a pit in the ground as a simple playground. By around age one, the baby could expect to receive very severe discipline.

At age fourteen, boys earned a loincloth in a ceremony

Women

Women were an essential part of Inca society. Their principal role in society was to care for their children, cook, weave, make chicha beer and work at the fields; however, they had many other household duties, such as cleaning, to make their lives after marriage very busy.

Marriage

Incan women were typically married at the age of sixteen. In Inca society, due to economic regulations, men of lower rank could only have one wife. The aristocracy, starting with the curaca

.

Trial marriages were typical within Inca culture. In this type of marriage, the man and woman would agree to try out being married to one another for a few years. At the end of this time, the woman could go home to her parents if she wished, and her husband could also send her home if he did not think it would work out. However, once the marriage was made final, they could only divorce if the woman was childless.

Women would almost always marry men in the same social class as them. However, while it was very rare for them to marry a man with a higher social ranking, it was still possible for some young women. The only way for a young woman to alter her social ranking would be if a man of higher ranking took notice of her.

In the Inca society, a wedding was not a joyous celebration. Instead, it was looked at more as a business-like agreement. Therefore, for the Inca, marriage was an economic agreement between two families. Once a woman was married, she was expected to collect food and cook, watch over the animals and the children. A woman’s household obligations would not change after she became pregnant. When she did find out she was pregnant she prayed and made offerings to an Inca god, Kanopa.

Arts

The Inca were a conquering society, and their expansionist assimilation of other cultures is evident in their artistic style. The artistic style of the Inca utilized the vocabulary of many regions and cultures, but incorporated these themes into a standardized imperial style that could easily be replicated and spread throughout the empire. The simple abstract geometric forms and highly stylized animal representation in ceramics, wood carvings, textiles and metalwork were all part of the Inca culture. The motifs were not as revivalist as previous empires. No motifs of other societies were directly used with the exception of Huari and Tiwanaku

.)

The Incan government controlled all clothing of their society. One would receive two outfits of clothing, one formal and one casual pair, and they would then proceed to wear those same outfits until they could literally be worn no longer. Since the government was in such strict control on their clothing, the Incans could not alter their clothing without the permission of the government.

Hairstyles

Discoveries have been made about the Incan hairstyles through studying their ancient mummies. It is believed that women of this culture had very long hair that they would most typically braid. Men on the other hand, would still have relatively long hair, yet would occasionally cut it with a certain type of knife. It has been thought that certain hairstyles may distinguish one class from another.

 was incorporated into the empire. Unlike the Chimú, the Inca do not seem to have regarded metals to be as precious as fine cloth. Nonetheless, the metalworks of the Incas were perhaps the most advanced in America. When the Spanish first encountered the Inca they were offered gifts of qunpi cloth.
Incan ceramics are usually very distinct and easy to recognize. The shapes of the vessels are highly standardized. The most typical Incan pottery would have a spherical body with a cone shaped base. This spherical body usually includes two vertical side handles with a tall neck and flaring rim. The Incans often would place animal heads on their pottery as well usually near the top of the vessel. There were also several other popular styles for Incan ceramics which included a shallow dish with a single bird head and handle, a pedestal beaker, and a single or double handled bottle.

Incans often decorated their ceramics with a multitude of images and colors. They usually decorated their pottery with bright colors of red, yellow, orange, black and white. Much like all other forms of Incan art, the pottery was often decorated with geometric shapes. The Incans would put diamonds, squares, checkers, triangles, circles and dots on almost all of their ceramic work. Other common themes were animals and insects like llamas, birds, jaguars, alpacas, bees, butterflies as well as block-like humans.

As part of a tax obligation to the commoners, mining was required in all the provinces. Even though the Inca Empire contained a lot of precious metals, the Incans did not value their metal as much as fine cloth. The Incans adopted much of their metal-working characteristics from the metalwork of Chimu. Because of their expertise in metalworking, after the fall of Chimu many metalworkers were taken back to the capital city of Cuzco to continue their metalworking for the emperor. Copper, tin, gold, and silver were all obtained from mines or washed from the river gravels. These metals would then be handed over to metallurgists. Because the Inca had a system that emphasized political and religious organization, there were many specialized artisans like metallurgists. There were also specialized weavers, cloth makers, pottery makers, and many more. Both copper and bronze would be used for basic farming tools or weapons. Some of the common bronze and copper pieces found in the Incan empire included sharp sticks for digging, club-heads, knives with curved blades, axes, chisels, needles and pins. All of these items would be forged by a metallurgist and then spread throughout the empire.

The Incans reserved their more precious metals for ornaments and decorations. Gold and silver were common themes throughout the palaces of Incan emperors. It was said that the walls and thrones were covered with gold and that the emperor dined on gold and silver service. These golden plated services would often be inlaid with llamas, butterflies or other creatures. Even beyond the gold and decoration of the emperor’s palace were the ornaments that decorated all of the temples throughout the empire. The temples of the Incans were strewn with sacred and highly precious objects. Headdresses, crowns, ceremonial knives, cups, and a lot of ceremonial clothing were all inlaid with gold or silver.

Many historians believe that the choice of gold was to distinguish the more “sacred” or “holy” pieces from others. The commonality of gold has much to do with the Incan religion surrounding the sun. Because of the beautiful reflection that gold casts, it gave the appearance of containing the sun, making the precious metal even more valued in a sun-obsessed society. Gold was reserved for the highest class of Incan society which consisted of priests, lords and of course the Sapa Inca or emperor.

Education


The Inca used quipu
Quipu
Quipus or khipus were recording devices used in the Inca Empire and its predecessor societies in the Andean region. A quipu usually consisted of colored, spun, and plied thread or strings from llama or alpaca hair. It could also be made of cotton cords...

 or bunches of knotted strings, for accounting and census purposes. Much of the information on the surviving quipus has been shown to be numeric data; some numbers seem to have been used as mnemonic labels, and the color, spacing, and structure of the quipu carried information as well. Since it isn't known how to interpret the coded or non-numeric data, some scholars still hope to find that the quipu recorded language.

The Inca depended largely on oral transmission as a means of maintaining the preservation of their culture. Inca education was divided into two distinct categories: vocational education for common people of Inca and highly formalized training for the nobility.

Medicine

The Inca made many discoveries in medicine. They performed successful skull surgery

Coca

 leaves were used to lessen hunger and pain, as they still are in the Andes. The Chasqui (messengers) chewed coca leaves for extra energy to carry on their tasks as runners delivering messages throughout the empire.

Recent research by Erasmus University and Medical Center workers Sewbalak and Van Der Wijk showed that, contrary to popular belief, the Inca people were not addicted to coca.

Another remedy was to cover boiled bark from a pepper tree and place it over a wound while still warm.

The Inca also used guinea pigs not only for food but for a so-called well-working medicine.

Religion

The belief system of the Incas was polytheistic. Inti, the Sun God, was the most important god, which the Incas believed was the direct ancestor of the Sapa Inca, the title of the hereditary rulers of the empire.

Other practices

The Inca practiced cranial deformation. They achieved this by wrapping tight cloth straps around the heads of newborns in order to alter the shape of their still-soft skulls. These deformations did not result in brain damage. Researchers at the Field Museum believe that the practice was used to mark different ethnicities across the Inca Empire.

Food and farming

It is estimated that the Inca cultivated around seventy crop species. The main crops were potato

.)

The Incan government controlled all clothing of their society. One would receive two outfits of clothing, one formal and one casual pair, and they would then proceed to wear those same outfits until they could literally be worn no longer. Since the government was in such strict control on their clothing, the Incans could not alter their clothing without the permission of the government.

Hairstyles

Discoveries have been made about the Incan hairstyles through studying their ancient mummies. It is believed that women of this culture had very long hair that they would most typically braid. Men on the other hand, would still have relatively long hair, yet would occasionally cut it with a certain type of knife. It has been thought that certain hairstyles may distinguish one class from another.

 was incorporated into the empire. Unlike the Chimú, the Inca do not seem to have regarded metals to be as precious as fine cloth. Nonetheless, the metalworks of the Incas were perhaps the most advanced in America. When the Spanish first encountered the Inca they were offered gifts of qunpi cloth.
Incan ceramics are usually very distinct and easy to recognize. The shapes of the vessels are highly standardized. The most typical Incan pottery would have a spherical body with a cone shaped base. This spherical body usually includes two vertical side handles with a tall neck and flaring rim. The Incans often would place animal heads on their pottery as well usually near the top of the vessel. There were also several other popular styles for Incan ceramics which included a shallow dish with a single bird head and handle, a pedestal beaker, and a single or double handled bottle.

Incans often decorated their ceramics with a multitude of images and colors. They usually decorated their pottery with bright colors of red, yellow, orange, black and white. Much like all other forms of Incan art, the pottery was often decorated with geometric shapes. The Incans would put diamonds, squares, checkers, triangles, circles and dots on almost all of their ceramic work. Other common themes were animals and insects like llamas, birds, jaguars, alpacas, bees, butterflies as well as block-like humans.

As part of a tax obligation to the commoners, mining was required in all the provinces. Even though the Inca Empire contained a lot of precious metals, the Incans did not value their metal as much as fine cloth. The Incans adopted much of their metal-working characteristics from the metalwork of Chimu. Because of their expertise in metalworking, after the fall of Chimu many metalworkers were taken back to the capital city of Cuzco to continue their metalworking for the emperor. Copper, tin, gold, and silver were all obtained from mines or washed from the river gravels. These metals would then be handed over to metallurgists. Because the Inca had a system that emphasized political and religious organization, there were many specialized artisans like metallurgists. There were also specialized weavers, cloth makers, pottery makers, and many more. Both copper and bronze would be used for basic farming tools or weapons. Some of the common bronze and copper pieces found in the Incan empire included sharp sticks for digging, club-heads, knives with curved blades, axes, chisels, needles and pins. All of these items would be forged by a metallurgist and then spread throughout the empire.

The Incans reserved their more precious metals for ornaments and decorations. Gold and silver were common themes throughout the palaces of Incan emperors. It was said that the walls and thrones were covered with gold and that the emperor dined on gold and silver service. These golden plated services would often be inlaid with llamas, butterflies or other creatures. Even beyond the gold and decoration of the emperor’s palace were the ornaments that decorated all of the temples throughout the empire. The temples of the Incans were strewn with sacred and highly precious objects. Headdresses, crowns, ceremonial knives, cups, and a lot of ceremonial clothing were all inlaid with gold or silver.

Many historians believe that the choice of gold was to distinguish the more “sacred” or “holy” pieces from others. The commonality of gold has much to do with the Incan religion surrounding the sun. Because of the beautiful reflection that gold casts, it gave the appearance of containing the sun, making the precious metal even more valued in a sun-obsessed society. Gold was reserved for the highest class of Incan society which consisted of priests, lords and of course the Sapa Inca or emperor.

Education


The Inca used quipu
Quipu
Quipus or khipus were recording devices used in the Inca Empire and its predecessor societies in the Andean region. A quipu usually consisted of colored, spun, and plied thread or strings from llama or alpaca hair. It could also be made of cotton cords...

 or bunches of knotted strings, for accounting and census purposes. Much of the information on the surviving quipus has been shown to be numeric data; some numbers seem to have been used as mnemonic labels, and the color, spacing, and structure of the quipu carried information as well. Since it isn't known how to interpret the coded or non-numeric data, some scholars still hope to find that the quipu recorded language.

The Inca depended largely on oral transmission as a means of maintaining the preservation of their culture. Inca education was divided into two distinct categories: vocational education for common people of Inca and highly formalized training for the nobility.

Medicine

The Inca made many discoveries in medicine. They performed successful skull surgery
Trepanation
Trepanning, also known as trephination, trephining or making a burr hole, is a surgical intervention in which a hole is drilled or scraped into the human skull, exposing the dura mater in order to treat health problems related to intracranial diseases.

Coca

 leaves were used to lessen hunger and pain, as they still are in the Andes. The Chasqui (messengers) chewed coca leaves for extra energy to carry on their tasks as runners delivering messages throughout the empire.

Recent research by Erasmus University and Medical Center workers Sewbalak and Van Der Wijk showed that, contrary to popular belief, the Inca people were not addicted to coca.

Another remedy was to cover boiled bark from a pepper tree and place it over a wound while still warm.

The Inca also used guinea pigs not only for food but for a so-called well-working medicine.

Religion

The belief system of the Incas was polytheistic. Inti, the Sun God, was the most important god, which the Incas believed was the direct ancestor of the Sapa Inca, the title of the hereditary rulers of the empire.

Other practices

The Inca practiced cranial deformation. They achieved this by wrapping tight cloth straps around the heads of newborns in order to alter the shape of their still-soft skulls. These deformations did not result in brain damage. Researchers at the Field Museum believe that the practice was used to mark different ethnicities across the Inca Empire.

Food and farming

It is estimated that the Inca cultivated around seventy crop species. The main crops were potato

The population of Tawantinsuyu is currently unknown. There are estimates ranging from as few as 4 million people to more than 37 million. The reason for these various estimates is that, despite that the Inca kept excellent census records using their quipus, knowledge of how to read them has been lost. Almost all of them had been destroyed by the Harns in the course of their conquest.

Childhood

Inca childhood was harsh by today's standards.

When a child was born, the Inca would wash the baby in cold water and wrap it in a quilt. Later, the baby was put in a pit in the ground as a simple playground. By around age one, the baby could expect to receive very severe discipline.

Women

Women were an essential part of Inca society. Their principal role in society was to care for their children, cook, weave, make chicha beer and work at the fields; however, they had many other household duties, such as cleaning, to make their lives after marriage very busy.

.

Trial marriages were typical within Inca culture. In this type of marriage, the man and woman would agree to try out being married to one another for a few years. At the end of this time, the woman could go home to her parents if she wished, and her husband could also send her home if he did not think it would work out. However, once the marriage was made final, they could only divorce if the woman was childless.

Women would almost always marry men in the same social class as them. However, while it was very rare for them to marry a man with a higher social ranking, it was still possible for some young women. The only way for a young woman to alter her social ranking would be if a man of higher ranking took notice of her.

In the Inca society, a wedding was not a joyous celebration. Instead, it was looked at more as a business-like agreement. Therefore, for the Inca, marriage was an economic agreement between two families. Once a woman was married, she was expected to collect food and cook, watch over the animals and the children. A woman’s household obligations would not change after she became pregnant. When she did find out she was pregnant she prayed and made offerings to an Inca god, Kanopa.

Arts

The Inca were a conquering society, and their expansionist assimilation of other cultures is evident in their artistic style. The artistic style of the Inca utilized the vocabulary of many regions and cultures, but incorporated these themes into a standardized imperial style that could easily be replicated and spread throughout the empire. The simple abstract geometric forms and highly stylized animal representation in ceramics, wood carvings, textiles and metalwork were all part of the Inca culture. The motifs were not as revivalist as previous empires. No motifs of other societies were directly used with the exception of Huari and Tiwanaku

One would receive two outfits of clothing, one formal and one casual pair, and they would then proceed to wear those same outfits until they could literally be worn no longer. Since the government was in such strict control on their clothing, the Incans could not alter their clothing without the permission of the government.

Hairstyles

Discoveries have been made about the Incan hairstyles through studying their ancient mummies. It is believed that women of this culture had very long hair that they would most typically braid. Men on the other hand, would still have relatively long hair, yet would occasionally cut it with a certain type of knife. It has been thought that certain hairstyles may distinguish one class from another.

 was incorporated into the empire. Unlike the Chimú, the Inca do not seem to have regarded metals to be as precious as fine cloth. Nonetheless, the metalworks of the Incas were perhaps the most advanced in America. When the Spanish first encountered the Inca they were offered gifts of qunpi cloth.
Incan ceramics are usually very distinct and easy to recognize. The shapes of the vessels are highly standardized. The most typical Incan pottery would have a spherical body with a cone shaped base. This spherical body usually includes two vertical side handles with a tall neck and flaring rim. The Incans often would place animal heads on their pottery as well usually near the top of the vessel. There were also several other popular styles for Incan ceramics which included a shallow dish with a single bird head and handle, a pedestal beaker, and a single or double handled bottle.

Incans often decorated their ceramics with a multitude of images and colors. They usually decorated their pottery with bright colors of red, yellow, orange, black and white. Much like all other forms of Incan art, the pottery was often decorated with geometric shapes. The Incans would put diamonds, squares, checkers, triangles, circles and dots on almost all of their ceramic work. Other common themes were animals and insects like llamas, birds, jaguars, alpacas, bees, butterflies as well as block-like humans.

As part of a tax obligation to the commoners, mining was required in all the provinces. Even though the Inca Empire contained a lot of precious metals, the Incans did not value their metal as much as fine cloth. The Incans adopted much of their metal-working characteristics from the metalwork of Chimu. Because of their expertise in metalworking, after the fall of Chimu many metalworkers were taken back to the capital city of Cuzco to continue their metalworking for the emperor. Copper, tin, gold, and silver were all obtained from mines or washed from the river gravels. These metals would then be handed over to metallurgists. Because the Inca had a system that emphasized political and religious organization, there were many specialized artisans like metallurgists. There were also specialized weavers, cloth makers, pottery makers, and many more. Both copper and bronze would be used for basic farming tools or weapons. Some of the common bronze and copper pieces found in the Incan empire included sharp sticks for digging, club-heads, knives with curved blades, axes, chisels, needles and pins. All of these items would be forged by a metallurgist and then spread throughout the empire.

The Incans reserved their more precious metals for ornaments and decorations. Gold and silver were common themes throughout the palaces of Incan emperors. It was said that the walls and thrones were covered with gold and that the emperor dined on gold and silver service. These golden plated services would often be inlaid with llamas, butterflies or other creatures. Even beyond the gold and decoration of the emperor’s palace were the ornaments that decorated all of the temples throughout the empire. The temples of the Incans were strewn with sacred and highly precious objects. Headdresses, crowns, ceremonial knives, cups, and a lot of ceremonial clothing were all inlaid with gold or silver.

Many historians believe that the choice of gold was to distinguish the more “sacred” or “holy” pieces from others. The commonality of gold has much to do with the Incan religion surrounding the sun. Because of the beautiful reflection that gold casts, it gave the appearance of containing the sun, making the precious metal even more valued in a sun-obsessed society. Gold was reserved for the highest class of Incan society which consisted of priests, lords and of course the Sapa Inca or emperor.

Education


The Inca used quipu

Quipus or khipus were recording devices used in the Inca Empire and its predecessor societies in the Andean region. A quipu usually consisted of colored, spun, and plied thread or strings from llama or alpaca hair. It could also be made of cotton cords...

 or bunches of knotted strings, for accounting and census purposes. Much of the information on the surviving quipus has been shown to be numeric data; some numbers seem to have been used as mnemonic labels, and the color, spacing, and structure of the quipu carried information as well. Since it isn't known how to interpret the coded or non-numeric data, some scholars still hope to find that the quipu recorded language.

The Inca depended largely on oral transmission as a means of maintaining the preservation of their culture. Inca education was divided into two distinct categories: vocational education for common people of Inca and highly formalized training for the nobility.

Medicine

The Inca made many discoveries in medicine. They performed successful skull surgery

Recent research by Erasmus University and Medical Center workers Sewbalak and Van Der Wijk showed that, contrary to popular belief, the Inca people were not addicted to coca.

Another remedy was to cover boiled bark from a pepper tree and place it over a wound while still warm.

The Inca also used guinea pigs not only for food but for a so-called well-working medicine.

Religion

The belief system of the Incas was polytheistic. Inti, the Sun God, was the most important god, which the Incas believed was the direct ancestor of the Sapa Inca, the title of the hereditary rulers of the empire.

Other practices

The Inca practiced cranial deformation. They achieved this by wrapping tight cloth straps around the heads of newborns in order to alter the shape of their still-soft skulls. These deformations did not result in brain damage. Researchers at the Field Museum believe that the practice was used to mark different ethnicities across the Inca Empire.

Food and farming
