The thesis concentrates on Hofors and a local trade union environment between 1917 and 1946, where important parts of the trade union’s power were held by parties to the left of the social democrats. The overall aim is to problemize and discuss the issue of what characterised and made possible this deviation from the usual picture of a trade union movement dominated by social democracy. What characterised the conditions in such a local trade union environment and to what extent can local norms and political culture be linked to the conditions and the development in the trade union movement in Hofors? The factors behind the radicalism in Hofors can be found in the local union and political context. The investigation points out the following main reasons: the left-wing local council of the Social Democratic Party and its successors’ organisational lead, the local labour council’s working method being close to what has been considered “social democratic”, their representatives being highly trusted in the local community, and the growth of a local radical tradition. The political culture and the norms that gradually developed were based on a left-wing social democratic tradition. The local council of the Social Democratic Party that left the party in 1917 to join the left-wing social democratic faction was the same local council, despite their names and change of parties in the 1920s and 1930s. It became the local labour movement’s bearer of traditions and represented the continuity in the local trade union environment, which contributed to the leftwing socialist project being long-lived in Hofors. The central aspects were the trade union work and the practical-concrete tradition that developed. Primarily through successful trade union work, the local labour council and its trade union representatives gained strong and long-term support from a large proportion of the local trade union movement’s members and the population of Hofors. Against this background it may be stated that, even though it was often impossible for the parties to the left of social democracy to maintain a local trade union and political power position that was stronger than that of the social democrats for a lengthy period of time, it was not entirely impossible. It may also be stated that for the trade union member as such, a communist or socialist party affiliation was not a real obstacle in the election of shop stewards. Their focus was primarily put on the would-be representatives’ personal qualities and ability to live up to the demands and expectations placed on them by the members, and not so much on their ideological persuasion.

La thèse représente une première tentative de construire un narratif sur la Ligue de la jeunesse communiste du Canada (fondée en 1923) pendant la période de l'entre-deux-guerres, jusqu'ici absente des recherches existantes sur le communisme ou le socialisme canadiens. La thèse porte sur l'évolution des relations entre la Ligue de la jeunesse communiste (LJC), l'Internationale communiste (ou Komintern) et l'Internationale des jeunes communistes, où les communistes soviétiques ont joué un rôle prédominant. Cette recherche met en lumière de nombreux changements mineurs et majeurs dans la politique de la LJC, façonnés par les contextes nationaux et internationaux dans lesquels l’organisation a dû agir. La thèse soutient que malgré un enthousiasme sincère pour la ligne de l'Internationale et l'expérience soviétique, les jeunes communistes canadiens souvent avait de la difficulté d’appliquer les directives de l'Internationale au Canada. Ni le Komintern, ni le mouvement communiste au Canada n'étaient monolithiques. Au contraire, il y a eu de nombreux conflits à trois niveaux: entre le mouvement communiste international et la Ligue; entre la Ligue et le Parti communiste du Canada (PCC); et entre les groupes locaux ou linguistiques de la Ligue et son leadeurship national. La répression de la gauche par l’État dans les années 1920s et 1930s, les problèmes de financement et le nombre de membres dérisoire ont également entravé la mise en œuvre des politiques de l’Internationale. En même temps, le faible niveau de contrôle permettait un certain degré de flexibilité et d’autonomie dans les politiques de la Ligue canadienne. Suivant la position de l’International des jeunes communistes, la jeunesse communiste canadienne a mis un accent particulier sur le militantisme anti-capitaliste et anti-impérialiste, puis anti-fasciste et anti-nazi. Cependant, la Ligue semblait avoir agi de manière indépendante en ce qui concerne les revendications immédiates de la jeunesse canadienne et les politiques culturelles, en particulier pendant la Grande Dépression. La Ligue s'est engagée conjointement avec d'autres organisations de jeunesse pour promouvoir les demandes immédiates des jeunes, même lorsque Moscou n’encourageait pas une telle stratégie. Les initiatives venaient souvent des organisateurs locaux, même si les autorités canadiennes étaient convaincues que Moscou était à l'origine de chaque action de la Ligue. Dans les années 1930 en particulier, la LJC, à travers un réseau d’organisations sociales et culturelles, a eu accès à des jeunes de différentes orientations politiques - la gauche socialiste, le centre-gauche et même les «forces bourgeoises». L’impact et la portée de la LJC ont encore été renforcés par la fait que les sympathisants de l'organisation appartenaient à des milieux sociaux divers et incluaient non seulement des jeunes travailleurs et fermiers, mais aussi les étudiants du secondaire et de l'université, les artistes, les sportifs et les jeunes cols blancs, dont beaucoup appartenaient à des organisations religieuses de jeunesse. Pour ces jeunes, la LJC était le lieu qui fournissait les solutions marxistes à des questions brulantes de l’époque, telles que le chômage des jeunes et l’absence de sécurité sociale, l’injustice sociale ou encore la montée du fascisme et de l’impérialisme au Canada et à l’étranger. / The dissertation represents the first attempt to construct a narrative about the Young Communist League of Canada (founded in 1923) during the inter-war period, so far absent in existing research on Canadian communism or socialism. The thesis focuses on the evolution of the relationship between the Young Communist League (YCL) and the Communist International and Young Communist International where Soviet Communists played a predominant role. It sheds light on numerous minor and major changes of policy shaped by the national and international contexts in which these organisations had to act. The dissertation argues that despite genuine enthusiasm toward the International’s line and the Soviet experience, Young Canadian Communists often found it difficult to implement the International’s directives in Canada. Neither the International nor the communist movement in Canada was monolithic. On the contrary, there appear to have been numerous conflicts on three levels: between the International and the League; between the League and the Communist Party of Canada; and between local or linguistic groups in the League and its national leadership. The state repression of the left during the whole inter-war period, derisory level of funding and membership numbers also impeded the implementation of the International’s policies. At the same time, the International’s weaker levels of control allowed for a certain degree of flexibility and autonomy in the Canadian League’s policies. Following the position of the Young Communist International, the Canadian communist youth placed special emphasis on anti-capitalist and anti-imperialist, and later anti-fascist and anti-Nazi, militancy. However, the League appeared to have acted independently as far as immediate demands of the youth and cultural policies were concerned, especially during the Great Depression era. The League engaged in joint activism with other youth organisations, even when Moscow did not encourage such strategy. The initiatives often came from local grassroots organizers, although Canadian authorities were convinced that Moscow was behind each and every action of the League. In the 1930s in particular the YCL, through a network of social and cultural organisations, gained access to youth of different political orientations – the socialist left, centre-left and even “bourgeois forces.” The YCL’s impact and outreach were further increased by the fact that the organisation’s sympathizers, if not members, belonged to diverse social backgrounds and included not only young workers and farmers but also High School and University students, artists, sportsmen, young white collars, many of them belonging to religious youth groups. For these young people, the YCL was the place that provided Marxist solutions to burning questions of the time such as youth unemployment and absence of welfare, social injustice, growth of fascism and imperialism in Canada and abroad.

as English abstract / Oppressed by the severe surveillance of the Japanese police in Taiwan, short-lived Taiwanese Communist Party (TCP) (1928-1931) marked a significant step in the Taiwan’s anti-Japanese movement and social thought. The TCP was the first political organization in Taiwan to put forward the slogan of Taiwan’s independence. Following the Comintern’s activation in the East in 1920s, the first contacts between the Taiwan’s leftists and the Comintern representatives took place in early 1920s. Starting from 1927, the Comintern pursued the policy of activation of the communist movement in the colonies and establishment of communist parties in these countries. Established on the Comintern directive in Shanghai with the help of the Chinese Communist Party (CCP) and being subordinated to the Japanese Communist Party (JCP), the TCP was developing quite independently under the leadership of Xie Xuehong and in the close alliance with the Taiwan Cultural Association and the Taiwan Peasants Union, until the end of 1930 when the TCP established a contact with the Far Eastern Bureau (FEB) of the Comintern through the TCP Shanghai representative, Weng Zesheng, who served as liaison with the Comintern. As the result, the Comintern activated its work toward Taiwan, started dispatching emissaries to Taiwan who in the framework of the Comintern’s rhetoric of that time promoted the Party’s reform to eliminate the “opportunistic errors”. The activation of the Party’s work followed, the Union for Reorganization was established. The Comintern did not have chance to adjust the activity of the reformed TCP as within few months after the beginning of actual interaction between the Comintern and the TCP, the TCP was destroyed by arrests. The thesis is devoted to the Comintern’s role in the TCP’s establishment, development, reform, establishment of the Union for Reorganization, the Party’s activation and destruction. The research is based on the TCP files deposited in the former archive of the Comintern. The documents include the correspondence of the representative of the TCP, Weng Zesheng, with the Comintern FEB. The correspondence between Weng Zesheng and the FEB sheds light on the inner-party processes in the TCP, clarifies the essence of the inner-party struggle and reform, and explores the role of personal relations in the inner-party struggle which resulted in the UFR establishment without direct involvement of the Comintern. The available now text of the consultations of Weng Zesheng with the CCP representative Qu Qiubai makes it possible to clarify the CCP’s involvement in the TCP’s development and reform and to conclude as to whose directive it was to commence the struggle against Xie Xuehong. The TCP’s history was short but very intensive. Abandoned by its superior, the JCP, and not having relations with the international communist leadership, the TCP suffered lack of the financial and ideological support, and was left for the mercy of unpredictable fate of the exhausting inner factional struggle, still was able to survive under the “white terror” until the Party’s reorganization in 1931. According to the research results, the TCP inner-party struggles during 1928-1931 were in fact the result of resistance to emigrant party groupings who were attempting to take control over the TCP’s Taiwan based Party organization. Neither the JCP and the CCP, nor the Comintern had a real opportunity to influence the activities of the Taiwan-based communists. Taiwan’s communists overseas used the Comintern’s rhetoric and their contacts with the Comintern and the CCP to promote their agenda in the inner-party struggle. The implementation of the plans of Weng Zesheng and the opponents of Xie Xuehong in Taiwan on the Party’s reform and activation led to the Party’s destruction by the Japanese administration.

La tesi si concentra sul Partito Nazionalista Cinese negli anni Venti come punto privilegiato di osservazione del cambiamento politico della Cina dopo la Prima guerra mondiale. Questo decennio rappresentò un momento di definizione identitaria sia per i comunisti sia per i nazionalisti. La storiografia ne ha sottolineato numerosi aspetti, ma si è finora occupata del periodo 1919-1928 come una preistoria degli anni Trenta piuttosto che come un autonomo segmento di storia cinese. Studi recenti hanno superato implicitamente questo approccio criticando due date periodizzanti fondamentali per il Novecento cinese: la nascita della Repubblica nazionalista (1911) e la nascita della Repubblica Popolare (1949). A metà tra queste due date, gli anni Venti sono emersi come snodo decisivo nel passaggio da impero a Stato nazionale, durante cui si definì un nuovo spazio di discussione politica. Questo processo, pur interno, subì l’influsso delle strategie internazionali di sovietici e statunitensi dando vita a una nuova visione non soltanto della rivoluzione ma anche dello Stato post-rivoluzionario. Le classi dirigenti nazionalista e comunista, durante la collaborazione, si rivelarono dinamiche e tale “competizione” si trasferì anche all’interno di ciascun movimento diventando un fattore determinante per il successo o il fallimento del partito inteso come moderna formazione politica. / The thesis focuses on the Chinese Nationalist Party in the 1920s as a special standpoint to analyze the political changes in China after the World War I. That decade was crucial for shaping the identity of nationalists and communists. Many works have already examined some aspects, but they mostly considered the years 1919-1928 as a pre-history of the Thirties rather than an autonomous part of Chinese history. Recent studies have overcome this approach by criticizing two of the main periodization in the Chinese twentieth century: the birth of the nationalist Republic (1911) and the birth of the People’s Republic (1949). Halfway, the 1920s stood out as a critical juncture in the transition from empire to nation-state. A new space of political discussion was defined. The process, albeit internal, was under the influence of the USSR and US international strategies and gave birth not only to a new vision of the revolution, but also to a vision of the post-revolutionary state. Also, the nationalist and communist leaderships turned out to be dynamic. That "competition" may be seen also within the two political movements and became a shaping factor for the success or failure of the party as a modern political formation.
