. "A titular see in various churches is an episcopal see of a former diocese that no longer functions, sometimes called a \"dead diocese\". The ordinary or hierarch of such a see may be styled a \"titular bishop\", \"titular metropolitan\", or \"titular archbishop\".The term is used to signify a diocese that no longer functionally exists, often because the diocese once flourished but the territory was conquered for Islam or no longer functions because of a schism."@en .
