Clan

A clan is a group of people united by actual or perceived kinship and descent. Even if lineage details are unknown, clan members may be organized around a founding member or apical ancestor. Clans, in indigenous societies, tend to be exogamous, meaning that their members cannot marry one another. Clans preceded more centralized forms of community organization and government, and exist in every country. Members may identify with a coat of arms or other symbol to show that they are an independent clan. The kinship-based bonds may also have a symbolic ancestor, whereby the clan shares a "stipulated" common ancestor that is a symbol of the clan's unity. When this "ancestor" is non-human, it is referred to as a totem, which is frequently an animal.
