Esta tese tem por objeto o Partido Operário Comunista (POC). Trata-se de uma organização da esquerda radical brasileira, atuante durante os chamados anos de chumbo da ditadura civil-militar brasileira (1968-1971) sobre a qual não há nenhum estudo acadêmico mais pormenorizado. O POC foi oficialmente fundado em um Congresso realizado em abril de 1968, na cidade de São Paulo, com a fusão de duas organizações anteriormente existentes, a Organização Revolucionária Marxista-Política Operária (POLOP) e a Dissidência Leninista do Partido Comunista Brasileiro do Rio Grande do Sul (DI-RS). A linha política adotada pelo novo partido foi estabelecida pelo Programa Socialista para o Brasil, para o qual a revolução brasileira deveria ser socialista, e conduzida por um partido de vanguarda da classe operária, que estaria à frente de uma aliança operário-camponesa, engrossada por elementos revolucionários da pequena-burguesia. Inicialmente resistente ao engajamento nas ações de guerrilha urbana, o POC procurou canalizar seus esforços para os movimentos de massa que estavam ascensão quando da sua fundação. Neste sentido, dirigiu a militância para o movimento operário de Contagem (MG) e Osasco (SP), onde ocorreram importantes mobilizações nesse período. A organização também procurou influenciar o movimento estudantil e, para isso criou o Movimento Universidade Crítica, MUC, também em 1968. No início de 1969, com o descenso desses movimentos devido também ao AI-5, o POC reconheceu ter colhido poucos frutos desses esforços, sobretudo no movimento operário, onde sua presença continuou esparsa. Neste ínterim, várias organizações da esquerda já estavam francamente engajadas em ações armadas, o que motivava uma dupla crítica no interior do POC: ineficácia nas ações de massa, e inexistência de ações de guerrilha. Ácidos debates internos passaram a ocorrer no seu interior, corroendo sua coesão. Este processo de luta política interna se prolongou por todo o ano de 1969, polarizando os militaristas contra os massistas. Trocas mútuas de acusações levaram este grupo a romper com o POC em março de 1970 e a recriar a antiga POLOP. Dentre os militantes remanescentes do POC ainda se manteve um caloroso debate em torno das duas idéias-força: militarismo versus massismo. Há de se dizer que, de forma esparsa, e sempre em associação a outras organizações, o POC já havia praticado algumas ações armadas, dirigidas para a obtenção de recursos financeiros. a partir de meados de 1970, na sequência de prisões de militantes das organizações militaristas, a polícia política atingiria em cheio o POC, levando ao seu desmantelamento no Brasil em junho de 1971. Nesta tese procurei compreender os pormenores internos de uma organização leninista, bem como a rotina da militância em meio a um contexto repressivo, apoiando na noção de cultura política de Serge Bernstein. Por essa razão busquei os relatos de ex-membros do partido, através dos quais pude conhecer suas memórias sobre esse período. / This thesis is engaged in the Communist Workers Party (POC). It is an organization of the Brazilian radical left active during the so-called \"years of lead\" the Brazilian civil-military dictatorship (1968-1971) on which there is no more detailed academic study. The POC was officially founded at a congress held in April 1968 in São Paulo, with the merger of two previously existing organizations, the Organization Revolutionary Workers Marxist-Policy (POLOP) and the Brazilian Communist Party\'s Leninist Dissent Rio Grande South (DI-RS). The political line adopted by the new party was established by the \"Socialist Program for Brazil\", for which the Brazilian revolution should be socialist, and led by a vanguard party of the working class, who would be the head of a worker-peasant alliance, thickened by revolutionary elements of the petty bourgeoisie. Initially resistant engagement in urban guerrilla actions, the POC sought to channel their efforts to the mass movements that were rising at the time of its foundation. In this sense, he directed militancy to the labor movement of Contagem (MG) and Osasco (SP), where there were important mobilizations that period. The organization also sought to influence the student movement and to this end has created the \"Movement University Critical,\" MUC, also in 1968. In early 1969, with the decline of these movements also due to AI-5, POC acknowledged harvested little fruit of these efforts, especially in the labor movement, where his presence remained sparse. Meanwhile, several organizations of the left were already openly engaged in armed actions, which motivated a double criticism within the POC: ineffectiveness in mass actions, and lack of guerrilla actions. Acids internal discussions began to take place inside, eroding its cohesion. This political infighting process lasted throughout the year 1969, polarizing the \"militarists\" against \"massistas\". mutual exchange of accusations led this group to break with the POC in March 1970 and re-create the old POLOP. Among the remaining militants POC still remained a heated debate around the two key ideas: militarism \"versus\" massismo. One has to say that, sparsely, and always in association with other organizations, the POC had practiced some armed actions aimed at obtaining financial resources. from the mid-1970s, following arrests of militants from militarist organizations, the political police would reach full POC, leading to their being dismantled in Brazil in June 1971. This thesis tried to understand the internal details of a Leninist organization, as well as the routine of militancy amid a repressive environment, supporting the political culture\'s notion of Serge Bernstein. Therefore sought the reports of former party members, through which I got to know his memories of that period.

The dissertation examines the roots of modernity at the turn of the 20th century through the prism of the relationship between nationalism and internationalism. This seemingly incompatible affiliation between the two ideological archenemies has produced one of the most intriguing paradoxes of modern history. While theoretically attempting to reject nationalism as a transient product of capitalism, Marxism has in practice oftentimes exploited its appeal and utilized its extensive institutional repertoire. The study traces the evolution of Marxism’s conceptualization of the nationality question—a slow shift from an outright rejection of nationalism to an acceptance of its progressive features, complexity, varieties and influences. Interweaving intellectual and cultural studies in history with the political and intellectual history of the European Left, the study offers an intricate narrative of the crossroads of two important ideologies in theory and practice. The dissertation’s comparative and transnational approach reveals several important hitherto superficially explored aspects of Marxism’s difficult dialogue with nationalism. Firstly, it re-evaluates Karl Marx and Friedrich’s views on the nationality question, from its outright denial to limited acceptance and application. Secondly, it re-examines the multitude of Social Democratic responses to nationalism before the Great War. The advent of mass politics and the popularization of Marxist ideas produced a range of diverse socialist responses to the national conundrum throughout Europe. A comparison of Western (French and German), East Central and Eastern European (Austrian, Polish and Russian) and Soviet attitudes highlights some of the startling similarities and differences between the various groups’ ideological constellations. Finally, the dissertation uses the case study of the Communist Workers’ Party of Poland (Komunistyczna Partia Robotnicza Polski, KPRP) to reveal certain insights about the cumulative heritage of Marxist thought on nationalism. An analysis of the KPRP reveals a lot not only about a national party’s struggles with nationalism (challenging many historiographical questions), but also about the diverse conceptualizations of Marx and Engels’ thought on nationalism, about European Social Democracy’s debates about the phenomenon, and about the Soviet nationality policy (within and outside the Soviet Union).

The purpose of this master dissertation is to highlight the historical role of the working class on the border of Rio Grande do Sul and Uruguay, specifically in the town of Santana do Livramento. In September 1950, in the context of elections for president, there was a dramatic episode in the town of Livramento - more specifically, at International Park, in the border with Rivera, Uruguayan city. The Communist Party was in illegality and in clandestinity and the police had warned them that they would not allowed actions of its militants - more clearly, they would not allowed to graffiti the candidates' names defended by the PCB. A group of communists, however, has decided to do some graffiti in the city and it is repressed. The form of repression occurs with the use of firearms and four militants were killed. This study aims to analyze the workers' struggle and the communists in Livramento, taking this episode, occurred in the city in September 1950, as emblematic of social and political struggle in the period. This paper focuses on the relationship between the union activities of the strikers from Armour‟s frigorific and the slaughter of these workers, as activists from PCB in 1950, at International Park. The anticommunist policy of President Eurico Gaspar Dutra (1946-1951) and its alignment with the Truman Doctrine, defended by the United States, are important for explaining the circumstances experienced by the gauchos Communists in 1950. The episode of the death of the communists was known as "The Slaughter of the four A's", because the four dead communists had their names started with the letter "A": Ari, Abdias, Aladdin and Aristides. / A presente dissertação de Mestrado procurou trabalhar a atuação histórica da classe operária na fronteira do Rio Grande do Sul, Brasil, com o Uruguai, especificamente, na cidade de Santana de Livramento. Em setembro de 1950, no contexto das eleições para Presidente da República, ocorreu um episódio dramático na cidade de Livramento mais especificamente, no Parque Internacional, limítrofe com Rivera, cidade uruguaia. O Partido Comunista estava na ilegalidade e na clandestinidade e a polícia avisara que não permitiria a atuação de seus militantes mais claramente, a pichação de nomes de candidatos defendidos pelo PCB. Um grupo de comunistas, no entanto, decide fazer pichações na cidade e é reprimido. A forma de repressão se dá com uso de armas de fogo e quatro militantes são mortos. O presente trabalho visou analisar as lutas operárias e comunistas em Livramento, tomando esse episódio ocorrido na cidade, em setembro de 1950, como emblemático da luta social e política no período, O trabalho tratou da relação entre a atividade sindical dos grevistas do frigorifico Armour e a chacina destes operários, já como militantes do PCB, em1950, no Parque Internacional. A política anticomunista do Presidente Eurico Gaspar Dutra (1946-1951) e o seu alinhamento com a Doutrina Truman, defendida pelos Estados Unidos, são vertentes importantes para a explicação da conjuntura vivida pelos comunistas gaúchos no ano de 1950. O episódio da morte dos comunistas ficou conhecido como A chacina dos quatro As , pois os quatro comunistas mortos tinham seus nomes iniciados com a letra A : Ari, Abdias, Aladim e Aristides.
