Tribe in the context of "Middle Ages"

Social stratification refers to a society's categorization of its people into groups based on socioeconomic factors like wealth, income, race, education, ethnicity, gender, occupation, social status, or derived power (social and political). It is a hierarchy within groups that ascribe them to different levels of privileges. As such, stratification is the relative social position of persons within a social group, category, geographic region, or social unit.

In modern Western societies, social stratification is defined in terms of three social classes: an upper class, a middle class, and a lower class; in turn, each class can be subdivided into an upper-stratum, a middle-stratum, and a lower stratum. Moreover, a social stratum can be formed upon the bases of kinship, clan, tribe, or caste, or all four.

An ethnicity or ethnic group is a group of people who identify with each other on the basis of perceived shared attributes that distinguish them from other groups. Attributes that ethnicities believe to share include language, culture, common sets of ancestry, traditions, society, religion, history, or social treatment. Ethnicities are maintained through long-term endogamy and may have a narrow or broad spectrum of genetic ancestry, with some groups having mixed genetic ancestry. Ethnicity is sometimes used interchangeably with nation, particularly in cases of ethnic nationalism. It is also used interchangeably with race although not all ethnicities identify as racial groups.

By way of assimilation, acculturation, amalgamation, language shift, intermarriage, adoption and religious conversion, individuals or groups may over time shift from one ethnic group to another. Ethnic groups may be divided into subgroups or tribes, which over time may become separate ethnic groups themselves due to endogamy or physical isolation from the parent group. Conversely, formerly separate ethnicities can merge to form a panethnicity and may eventually merge into one single ethnicity. Whether through division or amalgamation, the formation of a separate ethnic identity is referred to as ethnogenesis.

A taboo is a social group's ban, prohibition or avoidance of something (usually an utterance or behavior) based on the group's sense that it is excessively repulsive, offensive, sacred or allowed only for certain people. Such prohibitions are present in virtually all societies. Taboos may be prohibited explicitly, for example within a legal system or religion, or implicitly, for example by social norms or conventions followed by a particular culture or organization.

Taboos are often meant to protect the individual, but there are other reasons for their development. An ecological or medical background is apparent in many, including some that are seen as religious or spiritual in origin. Taboos can help use a resource more efficiently, but when applied to only a subsection of the community they can also serve to suppress said subsection of the community. A taboo acknowledged by a particular group or tribe as part of their ways aids in the cohesion of the group, helps that particular group to stand out and maintain its identity in the face of others and therefore creates a feeling of "belonging".

Human sacrifice is the act of killing one or more humans as part of a ritual, which is usually intended to please or appease gods, a human ruler, public or jurisdictional demands for justice by capital punishment, an authoritative/priestly figure, spirits of dead ancestors or as a retainer sacrifice, wherein a monarch's servants are killed in order for them to continue to serve their master in the next life. Closely related practices found in some tribal societies are cannibalism and headhunting. Human sacrifice is also known as ritual murder.

Human sacrifice was practiced in many societies, beginning in prehistoric times. By the Iron Age (1st millennium BCE), with the associated developments in religion (the Axial Age), human sacrifice was becoming less common throughout Africa, Europe, and Asia. During classical antiquity, it came to be looked down upon as barbaric. In the Americas, however, human sacrifice continued to be practiced, by some, to varying degrees until the European colonization of the Americas. Today, human sacrifice has become extremely rare.

In Archaic Greece, an amphictyony (Ancient Greek: ἀμφικτυονία, a "league of neighbors"), or Amphictyonic League, was an ancient religious association of tribes formed before the rise of the Greek polis.

The six Dorian cities of coastal southwest Anatolia and the twelve Ionian cities to their north that formed the Ionian League after a Meliac war in the mid-7th century BC were already of considerable antiquity when the first written records emerged.

A demonym (/ˈdɛmənɪm/; from Ancient Greek δῆμος (dêmos) 'people, tribe' and ὄνυμα (ónuma) 'name') or 'gentilic' (from Latin gentilis 'of a clan, or gens') is a word that identifies a group of people (inhabitants, residents, natives) in relation to a particular place. Demonyms are usually derived from the name of the place (hamlet, village, town, city, region, province, state, country, and continent). Demonyms are used to designate all people (the general population) of a particular place, regardless of ethnic, linguistic, religious or other cultural differences that may exist within the population of that place. Examples of demonyms include Cochabambino, for someone from the city of Cochabamba; Tunisian for a person from Tunisia; and Swahili, for a person of the Swahili coast.

Many demonyms function both endonymically and exonymically (used by the referents themselves or by outsiders); others function only in one of those ways.
