The National Liberation Front of Corsica - Union of Combatants (Corsican: Fronte di Liberazione Naziunale di a Corsica - Unione di i Cumbattenti; abbreviated FLNC-UC) is a Corsican nationalist paramilitary and guerrilla organisation.

The FLNC-UC formed in December 1999 following a merger of five Corsican nationalist armed groups: the FLNC-Canal Historique, the FLNC-5 May, Fronte Ribellu, and Clandestinu. These groups were in constant conflict with each other during the period of the Corsican conflict known as the "Fratricidal War" or "Years of Lead" until the Migliacciaru Accords of March 1999. Resistenza Corsa joined as its fifth and final merger in August 2003. The FLNC-UC, with the exception of a brief period of negotiations in the early 2000s resulting in the Matignon Accords, waged a continuous guerrilla war on French authorities until 2014, when the FLNC-UC officially disarmed amidst promises of negotiations by the government in Paris.

Throughout most of its early existence, the FLNC-UC also fought a feud with the FLNC-22 October, a group created in 2002 to protest what they perceived as the FLNC-UC's inaction. This continued, with an exception from 2009 to 2012 in which the two groups unified, until the two entered an alliance in 2021. In August 2026, these groups turned antagonistic towards each other again following an FLNC-UC press conference in which the group denounced the "community of destiny" doctrine, a doctrine written in the 1980s by the original FLNC which states that anyone in Corsica, regardless of national origin, could adopt Corsican language and culture and thus be considered Corsican.

The FLNC-UC holds many of the same goals as the original FLNC and its other successors, most notably the violent overthrow of French rule in Corsica and the establishment of an independent Corsican state. The FLNC-UC also holds environmentalist and agrarian philosophies, a pillar of Corsican nationalist movements since the 1970s, outlined in the 1980s by the FLNC's "defence of the land" doctrine. Nazione (called Corsica Libera until 2024) is considered to be the FLNC-UC's political wing.

History

Origins Corsica was annexed by the Kingdom of France in 1769 following an invasion of Pasquale Paoli's Corsican Republic, which had recently been established following the Corsican War of Independence. Corsican nationalists launched multiple rebellions in the years following this, but none were particularly successful with the exception of a British-supported revolt in 1794 resulting in the creation of the Anglo-Corsican Kingdom.

Corsicans have, for most of their history under French rule, felt alienated from the French mainland due to geography, language, and customs. From the introduction of French rule, Corsican government institutions had largely been run by small, local families of politicians called “clans”.Regionalism and Ethnic Nationalism in France: a Case Study of Corsica by John P. Loughlin (PDF) The early French governments tolerated the clans, preferring to leave Corsica's governance to the Corsicans. French officials in Corsica like the prefect were sidelined on the island, and the goal of the prefect was to stay out of Corsican politics most of the time, only providing insight or guidelines to the French government in Paris. Under Napoleon III, The French cabinet had begun a policy of appointing a Corsican deputy minister, and for most of the French Third Republic that minister was Emmanuel Arène. Known to the locals as “u re Manuele” (the king Emmanuel), who attempted to create a system of clanism where Corsican politicians would be more open to French authority. Regardless of his attempt, real power in Corsica remained with the local Conseil Général and the mayors, who often acted in their own interests and were hostile, sometimes even physically violent, to French authorities such as the prefect and the deputies.

By the 1900s, Corsica was slowly being brought into the sphere of metropolitan France. Large migrations, industrialization, and government subsidies allowed short-term economic growth in Corsica, causing many locals to adopt pro-French sentiment, not due to a shared national identity, but rather due to the economic growth from being a French territory. This was strengthened by the tragedy of World War I, which allowed Corsica and mainland France to share a sense of solidarity and pride due to the men from Corsica who fought in the war. Following the war, many Corsicans became worried over the growing threat of Mussolini’s Italian Irredentism, as Corsica was included in the claims of many Italian irredentists. After the outbreak of World War II, many Corsicans saw the war with Germany on the mainland as mostly irrelevant, fearing a possible Italian invasion more than a German one. Many Corsicans, despite the wish to remain French, largely still didn’t feel a national connection to mainland France due to a separate linguistic, historical, and cultural identity. Upon the fall of France in 1940, the new Vichy government made defending Corsica from the Italian threat a priority. Despite the insistence of French unity by Corsican citizens, many were only supportive of a French government to reject Italian sovereignty. Corsican prefect Paul Balley stated: “a Corsican who claims to be French is demonstrating not so much loyalty to France as rejection of Italy”.

Corsicans under the Fourth Republic were largely supportive of Charles de Gaulle, seeking economic interests from him. During the Algerian War and other colonial conflicts of the 1960s, Corsicans were drafted heavily, making up 22 percent of French colonial forces despite only being around 1% of all French citizens. This was done to bind Corsica to France through military service, though it also created a small sense of disdain amongst Corsicans. “Operation Corse”, an invasion of Corsica by soldiers attempting to reinstate de Gaulle into power, was supported by many Corsicans, and resistance to the landings were next to none. Despite this, de Gaulle's administration during the Fifth Republic caused relations between Corsicans and France to sour greatly. De Gaulle's opposition to regionalism and the establishment of a “strong state” caused Corsicans, who had been enjoyed Corsican self-government for the longest time, to feel betrayed by de Gaulle. This led to the slow adoption of armed struggle in Corsica.

Two major turning points in Corsican nationalist history occurred in the early 1970s. The first, the Red Mud Affair, was a series of grassroots actions and riots against the French government for their indifference to the dumping of waste by Italian company Montedison into Corsican waters. The second, the Aleria standoff, occurred in 1975. Corsican militants of by the paramilitary Corsican Regionalist Action, headed by brothers Max Simeoni and Edmund Simeoni, stormed a wine cellar in the town of Aleria and got held off by the French gendarmerie, resulting in the deaths of 2 gendarmes and the serious wounding of an ARC militant. These events inspired even further militaristic ideology within the Corsican nationalist movement, culminating with the creation of the National Liberation Front of Corsica (Fronte di Liberazione Naziunale di a Corsica, FLNC) on 5 May 1976. The FLNC formally began the Corsican conflict and waged a harsh guerrilla campaign for nearly 12 years, only briefly interrupted by a 1981-1982 ceasefire and the implementation of the Defferre Accords. In 1988, following the re-election of François Mitterrand to his position as President of France, the FLNC signed a controversial ceasefire and began to negotiate with the French government for an eventual peace.

This ceasefire resulted in a convoluted breakup of the FLNC, and two main organisations appeared from the collapse of the group, dubbed by the press as the FLNC-Canal Historique (Canale Storicu; FLNC-CS), the FLNC-Canal Habituel (Canale Abituale; FLNC-CA). the FLNC-CA, led by Alain Orsoni, maintained some communications with the French state, attempting to continue to original FLNC's negotiations for peace. These resulted in the 1992 Joxe Accords. Meanwhile, the FLNC-CS, led by co-leaders Charles Pieri and François Santoni, began an intense armed campaign against French control of the island. The FLNC-CS became famous for its harshly militaristic beliefs, and the two main FLNC dissidents engaged in a harsh military feud, with both the FLNC-CA and FLNC-CS committing ambushes and assassinations on each other. This sparked the beginning of a bloody period of the Corsican conflict marked by internal divisions and assassinations known as the Years of Lead.

The Years of Lead reached new levels in December 1995. The FLNC-CS was experiencing internal division due to proposed peace negotiations with the French government. A small number of anti-peace members split from the group and created Fronte Ribellu, which positioned itself as a group distant from the FLNC-CS and FLNC-CA's feud. These proposed negotiations began the Tralonca peace campaign, a messy and convoluted attempt at peace between France and the FLNC-CS that ultimately resulted in failure. Fronte Ribellu continued to exist in spite of this, however, and had become even more extreme and militaristic guerrillas engaged in a feud against the FLNC-CS. At the same time, the FLNC-CA declared their dissolution on 5 May 1996, the 20th anniversary of the FLNC's creation. Many members of the group opposed disollution, and created on the following day the FLNC-5 May (FLNC-5 Maghju, FLNC-5M). the FLNC-5M engaged in feuds with the FLNC-CS and later Fronte Ribellu.

Migliacciaru Accords and Foundation In September 1998, François Santoni left the FLNC-Canal Historique, citing political polarisation, the failure of the Tralonca peace campaign, and alleged mafia influence in Charles Pieri's inner circle. Santoni continuously antagonised the FLNC-CS and Pieri in multiple interviews and public appearances, and he even wrote a series of books detailing Pieri's alleged mafia dealings aided by his lawyer and Corsica Nazione leader Jean-Guy Talamoni. Fearing yet another split and further conflict, FLNC-CS officials organised the so-called "Fiumorbo Nationalist Collective" in December 1998 to spur reunification of the violently feuding Corsican nationalist movements. The Fiumorbo region of Corsica, located on the east side of the island, is considered to be a historic area for Corsican nationalism, as it is the birthplace of some of the earliest anti-colonial organisations on the island.Paci, Deborah. The Women of Corsican Nationalism: Between Tradition and Modernity. (PDF)

On 17 March 1999, the Fiumorbo Nationalist Collective organised a meeting in the village of Migliacciaru in Prunelli-di-Fiumorbo of the various Corsican nationalist organisations in order to create a dialogue for peace. Present at the meeting were representatives from the following:

The FLNC-CS The FLNC-CS's political wing A Cuncolta Indipendentista The FLNC-5M The FLNC-5M's political wing Corsica Viva Fronte Ribellu Rinnovu Naziunale, a political party created from Corsica Viva dissidents in 1998 (Rinnovu would later become the political wing of the FLNC-22 October) Union of the Corsican People The Corsican National Alliance, political wing of the armed group Resistenza, on ceasefire since 1995

At 3:00pm on that day, these representatives signed the Migliacciaru Peace Accords, which committed them to mending the fractured nationalist movement and ended the Years of Lead period. Notably absent from this meeting was Santoni's Presenza Naziunale political party, a group he created with fellow-FLNC-CS dissident Jean-Michel Rossi following his departure from the group in September. In June 1999, Santoni and Rossi created the extremist Armata Corsa guerrilla group and began waging open war with the newly formed "Fiumorbo coalition" of the FLNC-CS, FLNC-5M, and Fronte Ribellu.
