In the 20th century, ostensibly Communist governments espousing Marxism–Leninism and its variants came into power in parts of the world, first in the Soviet Union with the Russian Revolution of 1917, and then in portions of Eastern Europe, Asia, and a few other regions after World War II. Along with social democracy, communism became the dominant political tendency within the international socialist movement by the early 1920s. During most of the 20th century, around one-third of the world's population lived under communist governments. These governments were characterized by one-party rule and suppression of opposition and dissent. With the dissolution of the Soviet Union in 1991, several communist governments repudiated or abolished communism altogether. Afterwards, only a small number of communist governments remained, namely China, Cuba, Laos and Vietnam. While the emergence of the Soviet Union as the world's first nominally Communist state led to communism's widespread association with the Soviet economic model, several scholars posit that in practice, the model functioned as a form of state capitalism.
The history of the Portuguese Communist Party (Portuguese: Partido Comunista Português or PCP), spans a period of more than 85 years, since its foundation in 1921 as the Portuguese section of the Communist International (Comintern) to the present. The Party is still an active force within Portuguese society.
After its foundation, the party experienced little time as a legal party before it was forced underground after a military coup in 1926. After some years of internal reorganization, that adapted the PCP to its new clandestine condition and enlarged its base of support, the Party became a force in the opposition to the dictatorial regime led by António de Oliveira Salazar, despite being brutally suppressed several times during the 48 years of resistance and having spent several years with little connection with the Comintern and the World Communist Movement.
After the end of the dictatorship, with the Carnation Revolution in 1974, the party became a major political force within the new democratic regime, mainly among the working class. Despite being less influential since the fall of the Socialist bloc in eastern Europe, it still enjoys popularity in vast sectors of Portuguese society, particularly in the rural areas of the Alentejo and Ribatejo, and also in the heavily industrialized areas around Lisbon and Setúbal, where it holds the leadership of several municipalities.
He led of "Irkutsk Faction" and "Tuesday Faction", and "Kyongsong Communist Group" in Korean communist movement during Japan's colonial rule (1910–45). After the liberation of Korea, he participated in the formation of People's Republic of Korea in Seoul, but he strongly opposed the joint with the right-wing in South Korea. Eventually the government is dismissed. In the late 1940s, started the uprising and general strike in South Korea. In addition, he led factions involved in Jeju uprising. After returning to the failed uprising in South Korea, he go to North Korea for reunification talks, was remained in there. And his led Faction called "Domestic Faction" or "WPSK Faction" in Workers' Party of Korea. He led faction's Guerilla movements in the South continue until the Korean war.
After 1955 he was not seen again, and it is widely believed that he was eliminated by Kim Il-sung's security forces.
A means can be justified only by its end. But the end in its turn needs to be justified. From the Marxist point of view, which expresses the historical interests of the proletariat, the end is justified if it leads to increasing the power of man over nature and to the abolition of the power of man over man.
“We are to understand then that in achieving this end anything is permissible?” sarcastically demands the Philistine, demonstrating that he understood nothing. That is permissible, we answer, which really leads to the liberation of mankind. Since this end can be achieved only through revolution, the liberating morality of the proletariat of necessity is endowed with a revolutionary character. It irreconcilably counteracts not only religious dogma but every kind of idealistic fetish, these philosophic gendarmes of the ruling class. It deduces a rule for conduct from the laws of the development of society, thus primarily from the class struggle, this law of all laws.
“Just the same,” the moralist continues to insist, “does it mean that in the class struggle against capitalists all means are permissible: lying, frame-up, betrayal, murder, and so on?” Permissible and obligatory are those and only those means, we answer, which unite the revolutionary proletariat, fill their hearts with irreconcilable hostility to oppression, teach them contempt for official morality and its democratic echoers, imbue them with consciousness of their own historic mission, raise their courage and spirit of self-sacrifice in the struggle. Precisely from this it flows that not all means are permissible. When we say that the end justifies the means, then for us the conclusion follows that the great revolutionary end spurns those base means and ways which set one part of the working class against other parts, or attempt to make the masses happy without their participation; or lower the faith of the masses in themselves and their organization, replacing it by worship for the “leaders”. Primarily and irreconcilably, revolutionary morality rejects servility in relation to the bourgeoisie and haughtiness in relation to the toilers, that is, those characteristics in which petty bourgeois pedants and moralists are thoroughly steeped."
