After internal tensions with the leadership of the Front National (FN), a group of politicians from Provence, including Marie-France Stirbois, Jacques Bompard, and Patrick Louis, broke away from the FN in 2005 to join the Movement for France (MPF). Stirbois died in April 2006 from cancer. Bompard's association L'Esprit Public, which had been involved with the organisation of conferences since 2003, hosted in August 2008 a party conference featuring speakers from various far-right groups the likes of Bernard Antony (AGRIF), Nicolas Bay (MNR), Jacques Cordonnier (Alsace d'Abord), Philippe Vardon (Nissa Rebela), Laurent Gouteron (Bloc Identitaire), or Jeanne Smits (Présent).[1]
On 29 January 2010, the League of the South (LS) was officially declared to the Journal Officiel; the LS list (Front Régional-Nissa Rebela-PDF-MNR) won 2.69% of the vote in the 2010 regional election. The following 23 June, a party executive was appointed.[1]
Leader and former member of the National Assembly Jacques Bompard, who has stated his belief in the Great Replacement theory, has called resisting against its application a priority.[4][5] Bompard is also politically close to the national party Reconquête, led by 2022 presidential candidate and former journalist Éric Zemmour.[6] On February 14, 2023, the Global Project Against Hate and Extremism (GPAHE) released a report in which it classified the League of the South as an "anti-muslim," "anti-immigrant," and "anti-LGBTQ+" group.[7]
