The Tlingit clans of Southeast Alaska, in the United States, are one of the indigenous cultures within Alaska. The Tlingit people also live in the Northwest Interior of British Columbia, Canada, and in the southern Yukon Territory. There are two main Tlingit lineages or moieties within Alaska, which are subdivided into a number of clans and houses. Tlingit moieties The Tlingit people of Southeast Alaska have two moieties (otherwise known as descent groups) in their society, each of which is divided into a number of clans. Each clan has its own history, songs, and totems, and each forms a social network of extended families which functions as a political unit in Tlingit society. The two moieties of the Tlingit society are the Raven (Yéil) and Eagle/Wolf (Ch'aak'/Gooch). The latter has two names because its primary crest differs between the north and the south regions of Tlingit territory, probably due to influence from the neighboring tribes of Haida, Tsimshian and Nisga'a. Each moiety is further subdivided into clans, and each clan is subdivided into houses. Clan names, crests and political structure The Tlingit clans have names whose meaning typically reflects the foundation story of the clan. The clans are usually referred to in English by the name of their primary crest, such as Deisheetaan being called "Beaver Clan". This is not accurate since some crests may be held by multiple clans. Clans of opposite moieties occasionally claim the same crest, but such irregular ownership is usually due to a debt owed by some other clan; until the debt is paid, the clan holding the debt claims the crest of the clan which owes the debt, as a means of shaming it. Clan allegiance is governed through a matrilineal system; children are born to the mother's clan and gain their status within her family, including what was traditionally hereditary leadership positions. The parents are required to be from differing clans; the children are born from the father, but he has a lesser role in their rearing than does the mother's brothers. Not all clans listed below are extant today; some have been absorbed into other clans; others have died out due to the lack of female descendants, and a few have been lost to history. Not all the clans are independent, since clans formed in a long and fluid process. For instance, the Kak'weidí descend from the Deisheetaan. Some members claim that
