History of the French Communist Party
From Wikipedia, the free encyclopedia

The French Communist Party (French: Parti Communiste Français; abbreviated PCF) has been a part of the political scene in France since 1920, peaking in strength around the end of World War II. It originated when a majority of members resigned from the socialist French Section of the Workers' International (SFIO) party to set up the French Section of the Communist International (SFIC). The SFIO had been divided over support for French participation in World War I and over whether to join the Communist International (Comintern). The new SFIC defined itself as revolutionary and democratic centralist. Ludovic-Oscar Frossard was its first secretary-general, and Ho Chi Minh was also among the founders. Frossard himself resigned in 1923, and the 1920s saw a number of splits within the party over relations with other left-wing parties and over adherence to the Communist International's dictates. The party gained representation in the French parliament in successive elections, but also promoted strike action and opposed colonialism. Pierre Semard, leader from 1924 to 1928, sought party unity and alliances with other parties; but leaders including Maurice Thorez (party leader from 1930 to 1964) imposed a Stalinist line from the late 1920s, leading to loss of membership through splits and expulsions, and reduced electoral success. With the rise of Fascism this policy shifted after 1934, and the PCF supported the Popular Front, which came to power under Léon Blum in 1936. The party helped to secure French support for the Second Spanish Republic during the Spanish Civil War and opposed the 1938 Munich Agreement with Hitler. During this period the PCF adopted a more patriotic image, and favoured an equal but distinct role for women in the communist movement.
The party was banned in 1939 on the outbreak of World War II. Under Comintern direction the PCF opposed the war and may have sabotaged arms production. The leadership, threatened with execution, fled abroad. After the German invasion of 1940 the party failed to persuade the occupiers to legalise its activities, and while denouncing the war as a struggle between imperialists, began to organise opposition to the occupation. When Germany invaded the Soviet Union the next year, the Comintern declared Germany to be an enemy, and the PCF expanded its anti-German activities, forming the National Front movement within the broader Resistance and organising direct action and political assassinations through the armed Francs-Tireurs et Partisans (FTP) group. At the same time the PCF began to work with de Gaulle's "Free France", the London-based government in exile, and later took part in the National Council of the Resistance (CNR).
By the time the German occupation ended in 1944, the party had become a powerful force in many parts of France. It was among the leading parties in elections in 1945 and 1946, and entered into the governing Tripartite alliance with the socialist SFIO and the Christian democratic MRP. The Tripartite governments pursued social reforms and statism. However, amid concerns within France and abroad over the extent of communist influence, the PCF was excluded from government in May 1947. Under pressure from Moscow, the PCF thereafter distanced itself from other parties and focused on agitation within its trade union base. For the rest of the Fourth Republic period the PCF, led by Thorez and Jacques Duclos, remained politically isolated, still taking a Stalinist line, though retaining substantial electoral support.[1]
Although the PCF opposed de Gaulle's formation of the Fifth Republic in 1958, the following years saw a rapprochement with other left-wing forces and an increased strength in parliament. With Waldeck Rochet as its new secretary-general, the party supported François Mitterrand's unsuccessful presidential bid in 1965 and started to move apart to a limited extent from the Soviet Union. During the student riots and strikes of May 68, the party supported the strikes while denouncing the revolutionary student movements. After heavy losses in the ensuing parliamentary elections, the party adopted Georges Marchais as leader and in 1973 entered into a "Common Programme" alliance with Mitterrand's reconstituted Socialist Party (PS). Under the Common Programme, however, the PCF steadily lost ground to the PS, a process that continued after Mitterrand's victory in 1981.
Initially allotted a minor share in Mitterrand's government, the PCF resigned in 1984 as the government turned towards fiscal orthodoxy. Under Marchais the party continued loyal to the Soviet Union up to its fall in 1991, and made little move towards "Eurocommunism". Extensive reform of the party's structure and policies had to wait until 1994, when Robert Hue became leader. The party's renunciation of much traditional communist dogma after this did little to stem its declining popularity, although it entered government again in 1997 as part of the Plural Left coalition. Elections in 2002 gave worse results than ever for the PCF, now led by Marie-George Buffet. Under Buffet, the PCF turned away from parliamentary strategy and sought broader social alliances. It condemned the Nicolas Sarkozy government's response to riots in 2005 and adopted a more militant stance towards the European Union. Buffet's attempt to stand in the 2007 presidential election as a common candidate of the "anti-liberal left" had little success. To maintain a presence in parliament after 2007 the party's few remaining deputies had to group together with those from The Greens and others to create the Democratic and Republican Left group (GDR). Subsequently, a broader electoral coalition, the Left Front (FG), was formed including the PCF, Jean-Luc Mélenchon's Left Party (PG), Unitary Left, and others. The FG has continued up to the present and has brought the French communists somewhat better electoral results, at the price of some tension within the party and with other parties in the FG. With Pierre Laurent as leader since 2010, in a symbolic move the party no longer includes the hammer and sickle logo on its membership cards.
The French Communist Party was founded in December 1920 by a split in the socialist French Section of the Workers' International (SFIO), led by the majority of party members who supported membership in the Communist International (or "Comintern") founded in 1919 by Lenin after the Bolshevik Revolution in Russia.
The outbreak of World War I in 1914 sparked tensions within the SFIO, when a majority of the SFIO took what left-wing socialists called a "social-chauvinist" line in support of the French war effort. Gradually, anti-war factions gained in influence in the party and Ludovic-Oscar Frossard was elected general secretary in October 1918. Additionally, the success of the Bolshevik Revolution in Russia aroused hope for a similar communist revolution in France among some SFIO members.
After the war, the issue of membership in the new Communist International became a major issue for the SFIO. In the spring of 1920, Frossard and Marcel Cachin, director of the party newspaper L'Humanité, were commissioned to meet with Bolshevik leaders in Russia. They observed the second congress of the Communist International, during the course of which Vladimir Lenin set out the 21 conditions for membership. When they returned, Frossard and Cachin recommended that the party join the Communist International.
At the SFIO's Tours Congress in December 1920, this opinion was supported by the left-wing faction (Boris Souvarine, Fernand Loriot) and the 'centrist' faction (Ludovic-Oscar Frossard, Marcel Cachin), but opposed by the right-wing faction (Léon Blum). This majority option won three quarters of the votes from party members at the congress. The pro-Comintern majority founded a new party, known as the French Section of the Communist International (Section française de l'Internationale communiste, SFIC), which accepted the strict conditions for membership.
A majority of socialist parliamentarians and local officeholders were opposed to membership, particularly because of the Communist International's strict democratic centralism and its denunciation of parliamentarianism. These members went on to form a rump SFIO, which had a much smaller membership than the SFIC but which could count on a strong base of officeholders and parliamentarians.
The founders of the SFIC took with them the party paper L'Humanité, founded by Jean Jaurès in 1904, which remained tied to the party until the 1990s. In the General Confederation of Labour (CGT) trade unions, the Communist minority split away to form the United General Confederation of Labour (CGTU) in 1922.
The new communist party defined itself as a revolutionary party, which used legal as well as clandestine or illegal means. The party organization was run under strict democratic centralist precepts, until the 1990s: the minority factions were compelled to follow the majority faction, any organized factions or contrary opinions were forbidden, while membership was tightly controlled and dissidents often purged from the party.
Ho Chi Minh, who would create the Việt Minh in 1941 and then declare the independence of Vietnam, was one of its founding members.[2]
Marginalization (1922–1934)

In its early years, as the communists fought the SFIO for control of the French left, the new party was weakened and marginalized by a series of splits and expulsions.
The "bolshevization" or stalinization imposed by the Communist International, as well as Zinoviev's power over the Communist International, led to internal crises. "Bolshevization" implied not only the adoption of the political strategy of the Communist International but a reorganization of party's structure on the model of the Bolsheviks (discipline, local organization under the shape of "cells", ascent of a young political staff which came from the working-class).
The first secretary-general of the PCF, Ludovic-Oscar Frossard, was often reluctant to obey the directives of the Communist International. Indeed, the party leadership was opposed to the strategy of the "proletarian unique front". Furthermore, one of Frossard's internal opponents, Boris Souvarine, was a member of the secretariat of the Communist International. Frossard resigned and left the PCF in 1923 to found a dissident United Communist Party which later became the Communist Socialist Party (but Frossard himself rejoined the SFIO). The general secretariat of the Party was shared by Louis Sellier (center faction) and Albert Treint (left-wing faction). At the same time, Boris Souvarine was expelled from the Communist International and the PCF due to his sympathy for Leon Trotsky.
In the 1924 legislative election, the PCF won 9.8% of the vote and 26 seats, considerably weaker than the SFIO. But under the leadership of the left-wing faction, priority was given to general strikes and revolutionary actions rather than elections. In the French Parliament, the PCF's first elected deputies were opposed to the Cartel des Gauches coalition formed by the SFIO and the Radical Party, which governed between 1924 and 1926.
In order to reconcile the various factions of the party, Pierre Sémard, railroad worker and union activist, was chosen as the new secretary-general. He wanted to put an end to sectarianism, which was criticized by communist officeholders and leaders of the CGTU. Most notably, he proposed alliances with other left-wing parties (including the SFIO) in order to combat fascism. This strategy was criticized by the board of the Communist International as "parliamentarist". At the same time, the party campaigned against French colonialism in Morocco (the Rif War), leading to the detention of some PCF members, including Sémard. On his release from prison, he became more and more controversial. Only 11 PCF candidates were elected in the Chamber of Deputies in the 1928 election, although the PCF increased its support to 11%.
In 1927, in the Soviet Union, Josef Stalin sidelined his opponents (Zinoviev, Kamenev and Leon Trotsky) and imposed a strict "class against class" line on the Communist International. In France, a Stalinist committee took control of the PCF . Its most influential figures came from the Communist Youth, notably Henri Barbé and Pierre Célor. They applied the "class against class" political line of the Communist International, denouncing social democracy and the SFIO as akin to bourgeois parties. Simultaneously, the new leadership purged dissidents, like Louis Sellier, former secretary-general, who created the Worker and Peasant Party, which merged with the Communist Socialist Party to form the Party of Proletarian Unity (PUP). By the end of the 1920s, the party contained fewer than 30,000 members.
The collegial leadership of the party was divided between young leaders and more experienced politicians. The secretary for organization, Maurice Thorez, was chosen as the new secretary-general in 1930. In 1931, Barbé and Celor were accused of responsibility for excesses in the "class against class" strategy. Nonetheless, the strategy was continued.
Indeed, the Wall Street Crash of 1929 and the Great Depression, which affected France beginning in 1931, caused much anxiety and disturbance, as in other countries. As economic liberalism failed, many were eagerly looking for new solutions. Technocratic ideas were born during this time (Groupe X-Crise), as well as autarky and corporatism in the fascist movement, which advocated union of workers and employers. Some members were attracted to these new ideas, most notably Jacques Doriot. A member of the presidium of the executive committee of the Comintern from 1922 onwards, and from 1923 onwards the secretary of the French Federation of Young Communists, later elected to the French Chamber of Deputies from Saint-Denis, he came to advocate an alliance between the Communists and SFIO. Doriot was then expelled in 1934, and with his followers. Afterwards he moved sharply to the right and formed the French Popular Party, which would be one of the most collaborationist parties during the Vichy regime.
The PCF was the main organizer of a counter-exhibition to the 1931 Colonial Exhibition in Paris, called "The Truth about the Colonies". In the first section, it recalled Albert Londres and André Gide's critics of forced labour in the colonies and other crimes of the New Imperialism period; in the second section, it contrasted imperialist colonialism to "the Soviets' policy on nationalities". In 1934 the Tunisian Federation of the PCF became the Tunisian Communist Party.[3]
The PCF suffered substantial losses in the 1932 election, winning only 8% of the vote and 10 seats. The 1932 election saw the victory of another Cartel des gauches. This time, although the PCF did not participate in the coalition, it supported the government from the outside (soutien sans participation), similar to how the Socialists, prior to the First World War, had supported republican and Radical governments without participating.
The Communist Party attracted various intellectuals and artists in the 1920s, including André Breton, the leader of the Surrealist movement, Henri Lefebvre (who would be expelled in 1958), Paul Éluard, Louis Aragon, and others.
In the early 1930s, its Comintern-appointed coordinator became Ana Pauker, who will later become the Foreign Minister of Romania, being the first woman to hold this position.[4]
The Popular Front (1934–1939)
This second Cartel coalition fell following the far-right 6 February 1934 riots, which forced Radical Prime Minister Édouard Daladier to cede power to the conservative Gaston Doumergue. Following this crisis, the PCF, like the whole of the socialist movement, feared that France was on the verge of fascist takeover. Adolf Hitler's rise to power in 1933 and the destruction of the Communist Party of Germany following the 27 February 1933 Reichstag fire led Moscow and Stalin to change course, and adopt the popular front strategy whereby communists were to form anti-fascist coalitions with their erstwhile socialist and bourgeois enemies. Maurice Thorez spearheaded the formation of an alliance with the SFIO, and later the Popular Front in 1936.
During the Popular Front era (after 1934) the PCF rapidly grew in size and influence, its growth fueled by the popularity of the Comintern's Popular Front strategy, which allowed an anti-fascist alliance with the SFIO and the Radical Party. The PCF made substantial gains in the 1934 cantonal elections and established themselves as the dominant political force in working-class municipalities surrounding Paris (the Red Belt) in the 1935 municipal elections.
The Popular Front won the 1936 elections; the PCF itself made major gains – taking 15.3% and 72 seats. SFIO leader Léon Blum formed a Socialist-Radical government, supported from the outside by the PCF. However, the Popular Front government soon collapsed under the strains of domestic financial problems (including inflation) and foreign policy issues (the radicals opposed intervention in the Spanish Civil War while the socialists and communists were in favour), and was replaced by a moderate government led by Édouard Daladier.
As the only major communist party in western Europe that was still legal, the PCF played a major role in supporting the Spanish Second Republic during the Spanish Civil War, alongside the Soviet Union. Blum's government officially maintained a neutral policy of non-intervention, but in practice his government ensured the safe passage of aid and Soviet weapons to the besieged Spanish republicans. The PCF often played a major role in such actions, and it sent a number of French volunteers to fight for the republicans in the International Brigades. At the end of the conflict, the PCF organized humanitarian aid for Spanish refugees.
The PCF's 72 deputies (along with only three others) opposed the ratification of the Munich Accords, signed by Daladier and Neville Chamberlain. The PCF believed that the accords would allow Hitler to turn his attention eastwards, towards the Soviet Union.
On 12 August 1936, a party organization was formed in Madagascar, the Communist Party (French Section of the Communist International) of the Region of Madagascar.[5]
New social positions
The cross-class coalition of the Popular Front forced the Communists to accept some bourgeois cultural norms they had long ridiculed.[6] These included patriotism, the veterans' sacrifice, the honor of being an army officer, the prestige of the bourgeois, and the leadership of the Socialist Party and the parliamentary Republic. Above all the Communists portrayed themselves as French nationalists. Young Communists dressed in costumes from the revolutionary period and the scholars glorified the Jacobins as heroic predecessors.[7]
The Communists in the 1920s saw the need to mobilize young women, but saw them as auxiliaries to male organizations. In the 1930s there was a new model, of a separate but equal role for women. The Party set up the Union des Jeunes Filles de France (UJFF) to appeal to young working women through publications and activities geared to their interests. The Party discarded its original notions of Communist femininity and female political activism as a gender-neutral revolutionary. It issued a new model more attuned to the mood of the late 1930s and one more acceptable to the middle class elements of the Popular Front. It now portrayed the ideal Young Communist as a paragon of moral probity with her commitment to marriage and motherhood, and gender-specific public activism.[8]
World War II (1939–1945)
Before Operation Barbarossa (1939 – June 1941)
Germany and the Soviet Union signed the Molotov–Ribbentrop Pact in August 1939, forming neutrality between both ideological rivals. The non-aggression pact between the Nazis and Moscow dismayed many French communists, a number of whom rejected the pact. A fifth of the PCF's caucus left the party, forming a dissident parliamentary group.
Shortly after France entered World War II in September 1939, the PCF was declared a proscribed organisation by Édouard Daladier's government. At first the PCF reaffirmed its commitment to national defense, but after the Comintern addressed French Communists by declaring the war to be 'imperialist', the party changed its stance. PCF parliamentarians signed a letter calling for peace and viewed Hitler's forthcoming peace proposals favourably. The Comintern ordered the PCF leadership to flee to Belgium, while Maurice Thorez, on Georgi Dimitrov's orders, deserted the army and fled to Moscow in order to escape prosecution. The PCF became a clandestine organization, at first rather disorganized.[9] In France, the government dissolved all Communist-led local administrations, cracked down on communist trade unionists and targeted the L'Humanité newspaper.[10] The government decreed that any communist propaganda, assimilated to Nazi propaganda, would be punished by the death penalty. After Communist Party was dissolved by the government, the Communist group in the Chamber was replaced by the French Workers' and Peasants' Group, whose president was Arthur Ramette and whose general secretary was Florimond Bonte.
Domestically, the PCF led anti-war actions, but although the party published pacifist propaganda for soldiers they stopped short of inciting desertion. The role of the PCF in alleged sabotage operations, against armaments plants, has been a point of debate among historians. In 1951, A. Rossi listed a number of sabotage operations initiated by the PCF against armaments factories throughout France,[11] but later historians have downplayed the PCF's role in any such actions, stating that they were isolated cases.[12]
After the German invasion of France in 1940 and the ensuing Nazi occupation of France, the relationship between the Communists and the German occupiers fluctuated. The domestic leadership, led by Maurice Tréand with the knowledge of Jacques Duclos, petitioned the Germans to allow the republication of L'Humanité, which would take a neutral stance on the occupation. But these negotiations were a disaster for the party, as Hitler disavowed Otto Abetz and Vichy was successfully able to oppose the legalization of the PCF. Nevertheless, the PCF limited openly anti-German or anti-occupation actions and instead adopted virulently anti-British, anti-imperialist, anti-socialist and anti-Vichy/Pétain rhetoric which shied away from directly attacking the Nazi occupiers.[13] In return, Otto Abetz would have allowed for the liberation of over 300 communist prisoners.[14] Moscow later denounced the attempts of the PCF to lobby the Germans for the party's legalization. In August 1940, a new policy categorically forbade any expressions of solidarity with the occupiers and limited interactions between the PCF and the occupiers.
Simultaneously, however, many communists and PCF cells reorganized clandestinely and began organizing opposition to the Germans and Philippe Pétain's regime in Vichy. One of the major actions organized by the PCF against the occupation forces was a demonstration of thousands of students and workers, staged in Paris on 11 November 1940. In May 1941, the PCF helped to organize more than 100,000 miners in the Nord and Pas-de-Calais departments in a strike. On 26 April 1941, the PCF called for a National Front for the independence of France with the Gaullists.[15] The Vichy French police, and later the Germans, began to arrest and intern large number of communists.
Armed resistance (June 1941 – 1945)

When Germany invaded the Soviet Union in June 1941, Stalin ordered all communists to engage in the armed struggle against the new Nazi enemy. The PCF expanded Resistance efforts within France, notably advocating the use of direct action and political assassinations. In August 1941, Pierre Georges (Colonel Fabien) shot and killed a German naval officer in the Paris métro. In October, the Germans stepped up reprisal actions, ordering the execution of 22 interned communists at Châteaubriant including the 17-year-old Guy Môquet, later honoured as a hero of the resistance.
By late 1941 and early 1942, the PCF set up the Francs-Tireurs et Partisans (FTP), the armed faction of the communist-led National Front. At the same time, with Moscow's blessing, the PCF engaged in talks with Charles de Gaulle, the leader of Free France in London. The communists began cooperating with the Free French, while maintaining their distance from other resistance organizations in the north and the south—remaining independent of the Unified Movements of the Resistance (MUR), the structure organized by Jean Moulin which organized the southern resistance. The National Front, PCF and CGT participated in the creation of the National Council of the Resistance (CNR) in May 1943.
During this time period, the PCF was led by Jacques Duclos and Benoît Frachon, operating out of the Hurepoix region in the Essonne department south of Paris. Under their leadership, the PCF maintained strong internal cohesion under centralized authority, which greatly boosted their power and influence within the resistance movement. In the regions, local communists played significant roles in spearheading the resistance. Most famously, PCF activist Georges Guingouin organized and led the maquis in the Haute-Vienne (Limousin). Immigrant workers linked to the PCF partook in resistance operations through the FTP-MOI (Francs-tireurs et partisans – main-d'œuvre immigrée).
By 1944 the PCF had reached the height of its influence, and was powerful in large areas of the country through the Resistance units under its command. Some in the PCF wanted to launch a revolution as the Germans withdrew from the country, but the leadership, acting on Stalin's instructions, opposed this and adopted a policy of co-operating with the Allied powers and advocating a new Popular Front government. Many well-known figures joined the party during the war, including Pablo Picasso, who joined the PCF in 1944.

Provisional Government and the Fourth Republic (1945–1958)
The PCF at its peak and the Tripartite governments (1945–1947)
The Communists came out extraordinarily strengthened from the Resistance, in terms of both organisation and prestige. With the liberation of France in 1944, the PCF, along with other resistance groups, entered the government of Charles de Gaulle. As in post-war Italy, the communists were very popular and formed one of the major political forces in the country. The PCF was nicknamed the "party of the 75,000 executed people" (le parti des 75 000 fusillés) because of its important role during the Resistance.
By the close of 1945 party membership stood at half a million, an enormous increase from its pre-Popular Front figure of less than thirty thousand. In the first post-war elections for the unicameral interim Constituent National Assembly in October 1945, the PCF became the single largest party in France with 26.2% of the vote and 159 seats. In the June 1946 elections for another constituent assembly, the PCF placed second but remained strong with 26% and 153 seats. In the November 1946 elections, which elected the first legislature of the new French Fourth Republic, the PCF obtained its best result in its history – 28.3% and 182 seats.
Between 1944 and May 1947, the PCF participated in governing coalitions. Maurice Thorez served in cabinet between November 1945 and May 1947, including a period as vice-president of the council of ministers between January 1946 and May 1947. The PCF was a core component of the Tripartite alliance with the French Section of the Workers' International (SFIO) and the Christian democratic Popular Republican Movement (MRP) throughout this period. The tripartite governments under the provisional government (GPRF) and, after October 1946, the Fourth Republic, introduced a program of social reforms which laid the foundations of the French welfare state. This included the nationalization of strategic economic sectors (electricity (EDF) in 1946, the AGF insurance firm, the Crédit Lyonnais bank in 1945 and the Société Générale bank in 1946, as well as the nationalization of the car maker Renault). Trade union independence was guaranteed by the 1946 Charter of Amiens, a minimum wage established in 1947. This program comprised a substantial part of the so-called acquis sociaux (social rights) established in France during the second half of the twentieth century. Although the PCF were the largest party in most tripartite governments formed between 1945 and 1947, they never obtained the presidency of the council of ministers and only rarely held strategic cabinet portfolios such as finance, defense or the interior. PCF cabinet ministers usually held the public health, armaments, reconstruction, industrial production and labour portfolios. (Ambroise Croizat was minister of labour between 1945 and 1947.
The PCF and socialists played a major role in drafting the proposed April 1946 constitution, but it was rejected by voters in a referendum in May 1946, with 53% against.
The party's strong electoral showing and surge in membership led some observers, including American under-secretary of state Dean Acheson, to believe that a Communist takeover of France was imminent. A number of factors came to precipitate the expulsion of all PCF ministers from Paul Ramadier's government in May 1947. Abroad, the PCF refused to vote war credits for the First Indochina War and the violent repression of the Madagascar insurrection by the SFIO government created strains with its coalition partners. The United States were worried of communist power in France and Italy, and conditioned Marshall Plan aid to the expulsion of communists from governments in both countries. Domestically, large-scale strikes broke out at Renault factories in April 1947. The PCF was finally expelled from government in May 1947, the same time as the Italian Communist Party (PCI) were expelled from the Italian government. The PCF responded with a series of strikes and sabotages.
Political isolation (1947–1956)

The PCF remained isolated thereafter until François Mitterrand's electoral victory in 1981. It thus began to pursue a more militant policy, alienating it SFIO and prompting divisions and tensions on the French left. The PCF fell back on its union activities, at a time when the PCF tightly controlled the General Confederation of Labour (CGT), one of the largest and most militant unions in France.
The PCF, no longer restrained by the responsibilities of office, was free after 1947 to channel the widespread discontent among the working class with the poor economic performance of the new Fourth Republic. Furthermore, the PCF was under orders from Moscow to take a more radical course, reminiscent of the Third Period policy once pursued by the Comintern. In September 1947 several European Communist parties met in Szklarska Poręba in Poland, where a new international agency, the Cominform, was set up. During this meeting Andrei Zhdanov, standing in for Joseph Stalin, denounced the 'moderation' of the French Communists and their excessive participation in 'bourgeois' parliamentary governments, even though this policy had been previously approved by Moscow.
The PCF denounced the administration as the tool of American capitalism. Following the arrest of some steel workers in Marseille in November 1947, the CGT called a strike, as PCF activists attacked the town hall and other 'bourgeois' targets in the city. When the protests spread to Paris, and as many as 3 million workers joined the strike, Ramadier resigned.
This development was prevented by the determination of Robert Schuman, the new Prime Minister, and Jules Moch, his Minister of the Interior. It was also prevented by a growing sense of disquiet among sections of the labour movement with PCF tactics, which included the derailment in early December 1947 of the Paris-Tourcoing Express, which left twenty-one people dead. Sensing a change of mood, the CGT leadership backed down and called off the strikes. From this point forward the PCF moved into permanent opposition and political isolation, a large but impotent presence in French politics.
The party remained tightly controlled by Thorez, Duclos and Frachon (although the latter focused his activities on the CGT). Thorez remained secretary-general and uncontested leader of the PCF until his death in 1964, but he suffered hemiplegia in 1950 and was often in Moscow for treatment. Duclos, in his absence, became the de facto leader of the PCF. Under Duclos' leadership, potential rivals (André Marty and Charles Tillon) were sidelined and Auguste Lecœur, a rising star, was purged from the party in 1954.
The PCF remained a loyally Stalinist party throughout the period, and the PCF opposed the de-stalinization process begun by Moscow and other communist parties after Stalin's death in 1953. The PCF strongly supported the Soviet invasion of Hungary in 1956. A split occurred as Maoists left during the late 1950s. Some moderate communist intellectuals, such as historian Emmanuel Le Roy Ladurie, disillusioned with the policies of the Soviet Union, left the party after the violent suppression of Hungarian Revolution of 1956.
The PCF suffered losses in the 1951 election, winning 26.3% of the vote and 103 seats – a loss of 79 seats. The PCF and the Gaullist Rally of the French People (RPF) were sidelined and marginalized by the new governing coalition, the Third Force (a SFIO-Radical-MRP alliance). The Third Force's changes to the electoral law before the 1951 election were designed to weaken the PCF and RPF. Hence, the PCF lost 79 seats and won fewer seats than the SFIO (107) although it had 26.3% of the vote against only 15.4% for the SFIO. The PCF won 25.4% and 150 seats in the 1956 election. The PCF remained in opposition throughout this period, but as a major parliamentary force they contributed to the governmental instability of the Fourth Republic.
Jean-Paul Sartre, a "comrade" of the Communist party, actively supported the National Liberation Front (FLN) (the porteurs de valises networks, in which Henri Curiel took part). Long debates took place on the role of conscription. While this stance by the PCF may have helped it retain widespread popularity in metropolitan France, it lost it credibility on the radical left. Nevertheless, during his scholarship to study radio engineering in Paris (from 1949 to 1953), Pol Pot, like many other colonials educated in France (e.g. Ho Chi Minh in 1920), joined the French Communist Party.
In 1959 the PCF federation in Réunion was separated from the party, and became the Communist Party of Réunion.[16]
