Anthropological research reveals that most ethnic groups and nations are recent historical creations, our connection to people within these groups is relatively new, and our shared traditions are recently invented. in addition, most members will never meet each other. therefore, most nations today are:

1) achieved communities
2) conglomerates.
3) empires.
4) imagined communities.
5) nation-states.

Imagined communities

Explanation:

The concept of Imagined communities was developed in 1983 by historian Benedict Anderson, the concept of imagined communities refers to the fact that a nation "is imagined because the members of even the smallest nation will never know most of their fellow-members, meet them, or even hear of them, yet in the minds of each lives the image of their communion"

So, members of most ethnic groups and nations will never know each other face to face and yet, they identify themselves as part of a nation with common characteristics (and this is where nationalism appears).

Therefore, according to this concept, nations are a socially constructed group, imagined by people who perceive themselves as part of the group.

Thus, we can conclude that the question regarding anthropological research refers specifically to Imagined communities.

the incas have many rituals, cannibalism was always a very ritual thing, which was normally tied to sacrifices, warfare, death, and regeneration.

  the capac raymi was one of the most important ceremonies. it occurred around the summer solstice and was when they worshiped their sun god, also known as inti.

  the capacocho was another one of their most important ceremonies. it was when many children where selected to start their training, and these children where destined to become sacrificial blessings to their sun god, inti. being chosen for this ritual was a blessing.

  the eight day feast was a feast that lasted 8 days and, each day, the day began with a chanting at dawn. a follow up song at noon. which ended with complete silence at the end of the day. on this day, inca royalty was always dressed in silver and gold laced clothing.

  the combing of the hair was the most important ritual to young girls. this ritual was known as the coming of age ceremony, but only the most beautiful girls where chosen. in this ceremony, the girls chose their new name and where chosen as either brides, or princesses of rulers.
