Albigensian
Albigensian is a historical term referring to members of a Christian movement known as the Cathars who were active in the Languedoc region of southern France, especially near the city of Albi (Albegia). The name is attested in medieval sources and is commonly used in historical writing to designate Cathar communities in Occitania. In contemporary scholarship the term is often treated as archaic, with "Cathars" preferred for describing the broader movement.
Cathar belief combined dualist cosmology with a critique of the visible church; they taught a spiritual realm
From the late 12th century onward, the Catholic Church and the French crown pursued suppression of Catharism.
Today the term "Albigensian" is mainly of historical interest, with "Cathars" used in most modern accounts.
