In late 1947, Sheikh Touhami, an MTLD activist came from Béchar to Béni Abbès to found an office for his political party. The Abbabsa, who have already attended the exiled persons to their homes, did not hesitate to join the movement. The Bureau consisted of four people, Touhami Tayeb, Trabelsi Boufeldja, Abdellah Ben-cheikh and Benali Abderrahman, and remained in service until 1954, when the majority of activists transferred to the FLN. The Abbabsa participated in the war of National Liberation between 1954 and 1962.
