Background Karl Paul August Friedrich Liebknecht was born in Leipzig in 1871, the second of the five sons of
Wilhelm Liebknecht and his second wife Natalie (née Reh). His father, along with
August Bebel, was one of the founders and key leaders of the SPD and its precursor parties. Karl was baptized a
Lutheran in
St. Thomas Church. According to the Liebknecht family tradition, their lineage was directly descended from the theologian and founder of
Reformation,
Martin Luther. His godparents included
Karl Marx and
Friedrich Engels, who were not present at the baptism but had written declarations of their
godparenthood. As a child in the early 1880s, Liebknecht lived in
Borsdorf, now located on the eastern outskirts of Leipzig. His father had moved into a suburban villa there with August Bebel after they were expelled from Leipzig under the 'Lesser State of Siege', a provision of the
Anti-Socialist Laws directed against socialist, social democratic and communist associations and writings. The laws were in force from 1878 to 1890.
Studies In 1890 he graduated from the in Leipzig and on 16 August 1890 began studying law and administrative
cameral sciences at
Leipzig University. He studied there with jurist
Bernhard Windscheid, jurist and theologian
Rudolph Sohm, economist
Lujo Brentano, psychologist
Wilhelm Wundt, and art historian
Anton Springer. When the family moved to Berlin in October 1890, he continued his studies at the Friedrich Wilhelm University (now the
Humboldt University of Berlin), where he attended lectures by historian
Heinrich von Treitschke and economist
Gustav Schmoller. His certificate of academic completion is dated 7 March 1893. On 29 May 1893, he passed his examination for higher civil service posts (). Liebknecht then did his military service as a
one-year volunteer with the Guard Pioneer Battalion, a unit of the
Prussian Army, in Berlin in 1893 and 1894. After a long search for a position, he wrote his doctoral thesis "Compensation Enforcement and Compensation Pleas According to Common Law" (), which was awarded a magna cum laude by the Law and Political Science Faculty of the
Julius Maximilian University of
Würzburg in 1897. On 5 April 1899 he passed the examination for candidates to the higher civil service career path with a "good".
Legal career With his brother
Theodor and the socialist and Zionist
Oskar Cohn, he opened a law office in Berlin in 1899. In May of the following year he married Julia Paradies, with whom he had two sons, Wilhelm and Robert, and a daughter Vera. He joined the Social Democratic Party (SPD) in 1900 and in 1904, along with his colleague
Hugo Haase, he became known abroad as a political lawyer when he defended nine Social Democrats, among them the Pole
Franciszek Trąbalski, in the
Königsberg Secret Society trial. In other high profile criminal trials, he denounced the class-based justice of the empire and the brutal treatment of recruits in the military.
Treason trial From 1907 to 1910 Liebknecht was president of the
International Union of Socialist Youth, where he frequently spoke out against militarism. In 1907 he published
Militarism and Anti-Militarism as part of the SPD Youth. In the work he argued that against an external enemy, external militarism required chauvinistic obstinacy, and against an internal enemy, internal militarism required a lack of understanding or hatred of any progressive movement. Militarism also needed an impassive people so that the masses could be driven like a herd of cattle. Anti-militarist agitation, he said, must educate about the dangers of militarism, but it must do so within the framework of the law – a statement that the
Reich Court of Justice did not accept when Liebknecht was brought to trial for treason. He characterized the spirit of militarism with a reference to a remark by the Prussian Minister of War at the time, General
Karl von Einem, according to whom a soldier loyal to the king who shoots badly is preferable to one who shoots well but whose political convictions are questionable. On 17 April 1907 von Einem asked the Reich Prosecutor's Office to initiate criminal proceedings against Liebknecht on account of the pamphlet. The treason trial against Liebknecht took place before the
Reich Court of Justice, presided over by Judge Ludwig Treplin, on 9, 10 and 12 October 1907, with a large public presence. On the first day of the trial, Liebknecht said that imperial orders were null and void if their purpose was a breach of the constitution. (In the court's final ruling, it emphasized that the soldiers' unconditional duty of obedience to the emperor was a central provision of the constitution of the empire.) When Liebknecht responded to a question from the presiding judge by saying that various newspapers as well as the conservative politician
Elard von Oldenburg-Januschau were calling for a violent breach of the constitution, the judge cut him off, saying that he could allege that statements had been made in his courtroom that he had understood to be an incitement to a breach of the constitution. On the third day of the trial, Liebknecht was sentenced to one and a half years imprisonment () for acts preliminary to high treason.
Emperor Wilhelm II, who had a copy of
Militarism and Anti-Militarism, was informed about the Liebknecht trial several times by telegraph. He received a detailed report after the verdict was pronounced, but Liebknecht was not sent a copy of the written verdict until 7 November. His self-defense at the trial brought him considerable popularity among Berlin's workers, and a throng of people escorted him to prison.
Member of the Prussian Parliament and the Reichstag In 1908 Liebknecht became a member of the
Prussian House of Representatives even though he had not yet been released from prison in
Silesia. He was one of the first eight Social Democrats to become a member of the
Prussian state parliament, despite the
Prussian three-class franchise that gave more weight to higher-income voters. Liebknecht remained a member of the state parliament until 1916. His wife Julia died on 22 August 1911 after a gall bladder operation. Liebknecht married Sophie Ryss (1884–1964) in October 1912. Following the national
election of January 1912, Liebknecht, who was just 40, entered the Reichstag as one of the youngest SPD deputies. After unsuccessful attempts in 1903 and 1907, he won the "imperial constituency" of
Potsdam-
Spandau-Osthavelland, which until then had been the safe domain of the
German Conservative Party. In the Reichstag he immediately emerged as a staunch opponent of an army bill that would grant the emperor tax funds for armaments for the army and navy. He was also able to prove that the
Krupp company, a large steel and armaments firm, had illegally obtained economically important information by bribing employees of the War Ministry (the so-called Kornwalzer scandal).
First World War portrait, 1912 In the first half of July 1914 Liebknecht traveled to Belgium and France, where he met with socialist politicians
Jean Longuet and
Jean Jaurès and spoke at several events. He spent the French national holiday in Paris. He only became aware of the danger of a European war on 23 July, after the Austro-Hungarian ultimatum to
Serbia became known (the
July Crisis). At the end of July, he returned to Germany via Switzerland. On 1 August, the day mobilization was announced and war declared on
Russia, the Reichstag was summoned for a 4 August session. At the time there was still no question in Liebknecht's mind that "the rejection of war loans was self-evident and unquestionable for the majority of the SPD Reichstag faction". In the party's preparatory meeting on 3 August, there were, according to SPD representative
Wolfgang Heine, "vile, noisy scenes" because Liebknecht and 13 other deputies spoke out decisively against war loans. In the 4 August parliamentary session, however, the Social Democratic faction voted unanimously in favor of approving the loans that enabled the government to finance the initial war effort. Before the parliamentary group meeting on 3 August, those in favor of the approval had not expected such a success and had been by no means sure of even obtaining a majority in the SPD parliamentary group. Even during the break in the session after Reich Chancellor
Theobald von Bethmann Hollweg's speech, immediately before the vote, there was turmoil among the SPD deputies because some had demonstratively applauded the Chancellor's remarks. Liebknecht, who in the years before had repeatedly defended the unwritten rules of party discipline (i.e. unanimity) against representatives of the party's right wing, bowed to the decision of the majority and also voted for the government bill in the Reichstag's full session. Hugo Haase, who like Liebknecht had opposed the loan in the parliamentary group, agreed for similar reasons to read the statement of the parliamentary group majority, which was received with jubilation by the bourgeois parties. Liebknecht often thought about or discussed the events of 4 August, both privately and in public. He saw them as a catastrophic political and personal watershed. In 1916, he noted:"The defection of the majority of the parliamentary group came as a surprise even to the pessimists; the atomization of the hitherto predominant radical wing no less so. The importance of the credit approval in the shift of the faction's entire policy to the government camp was not obvious: there was still the hope that the decision of 3 August was the result of a temporary panic and would soon be corrected, or at least not repeated and even overridden. These and similar considerations, but also uncertainty and weakness, explained the failure of the attempt to win over the minority for a separate public vote. But what must not be overlooked is the sacred veneration that was still paid to party discipline at that time, and most of all by the radical wing that until then had had to defend itself ever more pointedly against breaches of discipline, or tendencies to break discipline, on the part of revisionist party members." Liebknecht expressly did not endorse a statement by Rosa Luxemburg and
Franz Mehring (its complete text is thought to have been lost), in which they threatened to leave the party because of its conduct. He "felt that it was a half-measure: in such a case one would already have had to leave." Luxemburg formed the International Group on 5 August 1914, to which Liebknecht along with ten other SPD leftists belonged and that attempted to form an inner-party opposition to the SPD's
Burgfriedenspolitik – a political truce under which the SPD voted for the war loans, all parties agreed not to criticize the government or the war, and the trade unions refrained from striking. In the summer and fall of 1914 Liebknecht and Luxemburg traveled throughout Germany to try to persuade – with little success – opponents of the war to reject financial support for the war. He also contacted other European workers' parties to show them that not all German Social Democrats were in favor of the war. Liebknecht's first major conflict with the new party line, one which attracted wide public attention, came when he traveled to Belgium between 4 and 12 September, in the middle of the 3-month long German invasion of the country. There he met with local socialists and was informed – in
Liège and
Andenne, among other places – about the mass reprisals ordered by the German military against alleged attacks by Belgian civilians. Liebknecht was accused in the press – including by Social Democratic papers – of "treason against the fatherland" and "party treason" and had to justify himself before the party executive on 2 October. After that he was all the more determined to vote against the new loan bill and to make it a demonstrative statement against the "unity phase's high tide" and for it to be the basis for rallying opponents of the war. In the run-up to the 2 December 1914 session, he tried and failed to win other opposition deputies over to his position.
Otto Rühle, who had previously assured Liebknecht that he would also openly vote no, was not able to withstand the party pressure and stayed away from the full session. Liebknecht was in the end the only deputy not to stand when Reichstag President
Johannes Kaempf called on the House to approve the supplementary budget by rising from their seats. At the next vote on 20 March 1915, Rühle voted with Liebknecht. Both had previously refused a request from about 30 other party members to leave the chamber with them during the vote. In April 1915 Mehring and Luxemburg published the journal . It was immediately confiscated by the authorities and appeared only once. Liebknecht, however, was not able to participate in the venture. Since 2 December 1914, police and military authorities had been considering how to stop his activities. In early February 1915, the high command of the
Prussian Army called him to serve in a construction battalion. He was therefore subject to the military laws that forbade any political activity outside his duties in the Reichstag and the Prussian Landtag. He went through the war on the Western and Eastern fronts as non-combatant soldier who was given leaves of absence for sessions of the Reichstag and Landtag. He nevertheless succeeded in expanding the International Group and organizing the SPD's staunchest opponents of the war throughout the Reich. That gave rise to the
Spartacus League on 1 January 1916; it was renamed the Spartacist League after its final break from social democracy in November 1918. On 12 January 1916, the SPD Reichstag membership expelled Liebknecht from its ranks by 60 votes to 25. In solidarity with him, Otto Rühle also resigned from the parliamentary group two days later. In March 1916 another 18 opposition deputies were expelled and subsequently formed the
Social Democratic Working Group, which Liebknecht and Rühle did not join. During the war Liebknecht had few opportunities to make himself heard in the Reichstag. Contrary to customary practice, the Reichstag president did not record in the official minutes the statement that Liebknecht had submitted in writing explaining his vote against the second war loan bill on 2 December 1914. Under various pretexts he was subsequently refused the parliamentary floor. It was not until 8 April 1916 that Liebknecht was able to speak from the rostrum on a lesser budget issue. This resulted in what deputy
Wilhelm Dittmann called a "chaotic and scandalous scene" such as never before witnessed in the Reichstag. Liebknecht was shouted down by liberal and conservative deputies raging "as if possessed", insulted as a "scoundrel" and an "English spy" and told to "shut his mouth". One member snatched Liebknecht's written notes from him and threw the sheets into the hall, and another had to be prevented by members of the Social Democratic Working Group from physically attacking him. At the Easter Youth Conference in
Jena, Liebknecht spoke to 60 young people on anti-militarism and the changing of social conditions in Germany. On 1 May 1916 he led an antiwar demonstration in Berlin that had been planned by the Spartacus League. Even though the demonstrators were surrounded by police, he began his oration with the words "Down with the war! Down with the government!" He was arrested and charged with treason. On the first day of the trial, which was intended to be an example for the socialist left,
a spontaneous solidarity strike organized by the
Revolutionary Stewards took place in Berlin with over 50,000 participants. Instead of weakening the opposition, Liebknecht's arrest gave new impetus to opposition to the war. On 23 August 1916 Liebknecht was sentenced to four years and one month in prison, which he served at
Luckau, Brandenburg from mid-November 1916 until his release under an amnesty on 23 October 1918. While Liebknecht was in prison, Hugo Haase, SPD chairman until March 1916, lobbied in vain for his release. In April 1917 the SPD split apart with the founding of the
Independent Social Democratic Party of Germany (USPD), which the Spartacus group joined in order to work within it toward revolutionary goals. Along with
Eduard Bernstein and the Catholic Reichstag deputy
Matthias Erzberger of the
Centre Party – who like Liebknecht was later murdered by right-wing extremists – Liebknecht was one of the very few German parliamentarians to publicly denounce the human rights violations of Germany's
Turkish-Ottoman allies such as the
Armenian genocide and the brutal crackdown on other non-Turkish minorities, particularly in
Syria and
Lebanon. This practice was tacitly approved both by the liberal parties and by the majority SPD, which was politically allied with the
Young Turk party
CUP. In some cases support was even publicly justified on the grounds of Germany's strategic interests and the alleged existential threat to
Turkey from Armenian and Arab terrorism.
November revolution 1918 . This photograph was later reproduced in KPD propaganda. Liebknecht was released from prison on 23 October 1918 as part of a general amnesty that the Reich government hoped would act as a relief valve for the pre-revolutionary mood in the country. The hope proved illusory, since in Berlin, where Liebknecht went immediately, he was greeted by a cheering crowd at the
Anhalter Station. A march set off in the direction of the Reichstag building but was pushed eastward by the Berlin police. In front of the Russian Embassy Liebknecht gave a speech in which he proclaimed: "Down with the
Hohenzollerns! Long live the social republic of Germany!" The embassy, which since the Russian
October Revolution of 1917 was representing a communist led country, then gave a reception in his honor. Liebknecht set about reorganizing the Spartacus League, which then emerged as a political organization in its own right. He urged the Revolutionary Stewards, which had organized the January strike, and both the USPD's rank and file and the Spartacus League to jointly coordinate preparations for a nationwide revolution. They planned a simultaneous general strike in all major cities and parades of armed strikers in front of the barracks of army regiments in order to persuade them to either join or lay down their arms. The Stewards, guided by workers' sentiment in the factories and fearing an armed confrontation with army troops, postponed the date set for the revolution several times, finally to 11 November 1918. Liebknecht though was unable to win acceptance in his party for the plans. On 30 October 1918 the central executive committee of the USPD, whose members were thinking more of a revolution by peaceful means, rejected his ideas, as did a meeting between the USPD and the Revolutionary Stewards on 1 November. On 8 November the revolution sparked by the
sailors' uprising in Kiel spread across Germany independently of Liebknecht's plans. Berlin's Revolutionary Stewards and USPD representatives called on their supporters to join the marches planned for the following day. On 9 November masses of people poured into the center of Berlin from all directions. From Gate 4 of the Berlin Palace, standing at the large window of the second floor, Liebknecht proclaimed the "Free Socialist Republic of Germany". Earlier that day
Philipp Scheidemann of the SPD had
proclaimed the "German Republic" from the Reichstag building. Liebknecht then became the spokesman for the revolutionary left. In order to push the November Revolution in the direction of a socialist soviet republic, he and Rosa Luxemburg began publishing a daily newspaper,
Die Rote Fahne ('The Red Flag'). In the ensuing disputes, however, it soon became apparent that most workers' representatives in Germany were pursuing social democratic rather than socialist goals. At the
Congress of Workers' and Soldiers' Councils of 16–20 December 1918, a majority advocated early parliamentary elections and thus self-dissolution of the councils. Liebknecht and Luxemburg were excluded from participation. Since December 1918,
Friedrich Ebert (SPD), head of the
Council of the People's Deputies that was acting as Germany's interim government, had been trying to take power away from the council movement with, if necessary, the help of the army. He was doing this in accordance with the secret
Ebert-Groener pact, under which
Wilhelm Groener, Quartermaster General of the German Army, had assured Ebert of the army's loyalty, in return for which Ebert had promised among other things to take prompt action against leftist uprisings. Ebert had troops assembled in and around Berlin for this purpose. On 6 December 1918 he attempted to use the military to prevent the Reich Congress of Workers' and Soldiers' Councils from taking place and, after that failed, to weaken the resolution the Congress had made for disempowering the military. On 24 December 1918, during the
Berlin Christmas battles, he used military force for the first time, directing it against the
People's Navy Division. It was close to the revolutionary Kiel sailors and was supposed to protect the Reich Chancellery for the Ebert government but was not prepared to leave its positions without pay. As a result of Ebert's successful military intervention against it, the three USPD representatives on the Council of People's Deputies resigned on 29 December, after which the council was made up of five SPD representatives. The Spartacists, who were gaining popularity throughout the Reich, made use of the military intervention to plan the founding of a new, left-wing revolutionary party and invited their supporters to its founding congress in Berlin at the end of December 1918. On 1 January 1919, the
Communist Party of Germany (KPD) introduced itself to the public. Beginning on 8 January, Liebknecht and other KPD members participated in the
Spartacist uprising which began with a general strike and the occupation of several Berlin newspaper buildings. Liebknecht joined the strike leadership and, against the advice of Rosa Luxemburg, called for an armed insurrection to overthrow the Ebert government. KPD delegates tried without success to persuade some regiments stationed in and around Berlin to defect, and with only minimal support from the mass of the working classes of Berlin, the uprising failed to gain ground. When the government called out the military against the insurgents on 11 January, they were quickly overwhelmed. The total death toll is estimated at around 180. == Death ==
