Rosa Luxemburg was a Polish and naturalised-German revolutionary socialist, orthodox Marxist, and anti-War activist during the First World War. She became a key figure of the revolutionary socialist movements of Poland and Germany during the late 19th and early 20th century, particularly the Spartacist uprising.
The Communist Party of Germany was a major far-left political party in the Weimar Republic during the interwar period, an underground resistance movement in Nazi Germany, and a minor party in West Germany during the postwar period until it was banned by the Federal Constitutional Court in 1956.
Eduard Bernstein was a German social democratic Marxist theorist and politician. A member of the Social Democratic Party of Germany (SPD), Bernstein had held close association to Karl Marx and Friedrich Engels, but he began to identify what he believed to be errors in Marxist thinking and began to criticize views held by Marxism when he investigated and challenged the Marxist materialist theory of history. He rejected significant parts of Marxist theory that were based upon Hegelian metaphysics and rejected the Hegelian perspective of an immanent economic necessity to socialism.
Ferdinand August Bebel was a German socialist politician, writer, and orator. He is best remembered as one of the founders of the Social Democratic Workers' Party of Germany (SDAP) in 1869, which in 1875 merged with the General German Workers' Association into the Socialist Workers' Party of Germany (SAPD). During the repression under the terms of the Anti-Socialist Laws, Bebel became the leading figure of the social democratic movement in Germany and from 1892 until his death served as chairman of the Social Democratic Party of Germany.
Clara Zetkin was a German Marxist theorist, communist activist, and advocate for women's rights.
Karl Heinrich Otto Rühle was a German Marxist active in opposition to both the First and Second World Wars as well as a council communist theorist.
Revolutionary defeatism is a concept made most prominent by Vladimir Lenin in World War I. It is based on the Marxist idea of class struggle. Arguing that the proletariat could not win or gain when fighting a war under capitalism, Lenin declared its true enemy is the imperialist leaders who sent their lower classes into battle. Workers would gain more from their own nations' defeats, he argued, if the war could be turned into civil war and then international revolution.
Internationalist and defencist were the broad opposing camps in the international socialist movement during and shortly after the First World War. Prior to 1914, anti-militarism had been a key principle among most European socialist parties. Leaders of the Second International had even suggested that socialist workers might foil a declaration of war by means of a general strike.
Socialist patriotism is a form of patriotism promoted by Marxist–Leninist movements. Socialist patriotism promotes people living within Marxist–Leninist countries to adopt a "boundless love for the socialist homeland, a commitment to the revolutionary transformation of society [and] the cause of communism". Marxist–Leninists claim that socialist patriotism is not connected with nationalism, as Marxists and Marxist–Leninists denounce nationalism as a bourgeois ideology developed under capitalism that sets workers against each other. Socialist patriotism is commonly advocated directly alongside proletarian internationalism, with communist parties regarding the two concepts as compatible with each other. The concept has been attributed by Soviet writers to Karl Marx and Vladimir Lenin.
Internationalism is a political principle that advocates greater political or economic cooperation among states and nations. It is associated with other political movements and ideologies, but can also reflect a doctrine, belief system, or movement in itself.
The Zimmerwald Conference was held in Zimmerwald, Switzerland, from September 5 to 8, 1915. It was the first of three international socialist conferences convened by anti-militarist socialist parties from countries that were originally neutral during World War I. Forty-two individuals and eleven organizations participated. Those participating in this and subsequent conferences held at Kienthal and Stockholm are known jointly as the Zimmerwald movement.
Karl Paul August Friedrich Liebknecht was a German revolutionary socialist and anti-militarist. A member of the Social Democratic Party of Germany (SPD) beginning in 1900, he was one of its deputies in the Reichstag from 1912 to 1916, where he represented the left-revolutionary wing of the party. In 1916 he was expelled from the SPD's parliamentary group for his opposition to the Burgfriedenspolitik, the political truce between all parties in the Reichstag while the war lasted. He twice spent time in prison, first for writing an anti-militarism pamphlet in 1907 and then for his role in a 1916 antiwar demonstration. He was released from the second under a general amnesty three weeks before the end of the First World War.
Left communism, or the communist left, is a position held by the left wing of communism, which criticises the political ideas and practices espoused by Marxist–Leninists and social democrats. Left communists assert positions which they regard as more authentically Marxist than the views of Marxism–Leninism espoused by the Communist International after its Bolshevization by Joseph Stalin and during its second congress.
Proletarian nation was a term used by 20th century Italian nationalist intellectuals such as Enrico Corradini to refer to Italy and other nations that they regarded as being productive, morally vigorous, and inclined to bold action, which they considered to be characteristics associated with the proletariat. Corradini admired revolutionary proletarian movements such as syndicalism for their tactics, although he opposed their goals, and he wanted to inspire a radical nationalist movement that would use similar tactics in service of different goals: a movement that would advocate imperialist war in place of class revolution, while maintaining the same methods of "maximum cohesion, concentration of forces, iron discipline and utter ruthlessness." Corradini associated the concept of proletariat with the economic function of production, arguing that all producers are in a moral sense proletarian, and he believed that all producers should be at the forefront of a new imperialist proletarian nation.
Revolutionary socialism is a political philosophy, doctrine, and tradition within socialism that stresses the idea that a social revolution is necessary to bring about structural changes in society. More specifically, it is the view that revolution is a necessary precondition for transitioning from a capitalist to a socialist mode of production. Revolution is not necessarily defined as a violent insurrection; it is defined as a seizure of political power by mass movements of the working class so that the state is directly controlled or abolished by the working class as opposed to the capitalist class and its interests.
World revolution is the Marxist concept of overthrowing capitalism in all countries through the conscious revolutionary action of the organized working class. For theorists, these revolutions will not necessarily occur simultaneously, but where and when local conditions allow a revolutionary party to successfully replace bourgeois ownership and rule, and install a workers' state based on social ownership of the means of production. In many Marxist schools, such as Trotskyism and Communist Left, the essentially international character of the class struggle and the necessity of global scope are critical elements and a chief explanation of the failure of socialism in one country.
The Spartacus League was a Marxist revolutionary movement organized in Germany during World War I. It was founded in August 1914 as the International Group by Rosa Luxemburg, Karl Liebknecht, Clara Zetkin, and other members of the Social Democratic Party of Germany (SPD) who were dissatisfied with the party's official policies in support of the war. In 1916 it renamed itself the Spartacus Group and in 1917 joined the Independent Social Democratic Party of Germany (USPD), which had split off from the SPD as its left wing faction.
Proletarian internationalism, sometimes referred to as international socialism, is the perception of all proletarian revolutions as being part of a single global class struggle rather than separate localized events. It is based on the theory that capitalism is a world-system and therefore the working classes of all nations must act in concert if they are to replace it with communism.
Georg Ledebour was a German socialist politician and journalist.
The Junius Pamphlet was a text written by Rosa Luxemburg in 1915 while she was in prison, against the brutality of the First World War. The actual title of the work was The Crisis of German Social Democracy but she used the pen-name “Junius” to avoid prosecution, and this became the basis of the work's popular name. The name “Junius” was apparently a reference to Lucius Junius Brutus, a hero of the Roman Republic. The pseudonym also echoed a name used to sign political polemics against King George III of England, known as the Letters of Junius.
