In 1878, Bismarck's government implemented extraordinary laws, and the majority of Social Democratic Party members fought heroically. This greatly inspired and educated Ka Liebknecht. The growth of Ka Liebknecht was also cordially cared for and taught by Marx and Engels. In their letters to Wilhelm Liebknecht and his wife, Marx and Engels often asked about Ka Liebknecht's growth and gave encouragement and spur. The care of the revolutionary tutor, the influence of the family, and the education of class struggle made Ka Liebknecht take part in revolutionary activities during his studies in middle school and university, publicize Marxism among his classmates, distribute revolutionary leaflets, expose the internal and external policies of the reactionary government, and attack Juncker and the bourgeoisie for their atrocities in oppressing the people.

In the same year, at the German Party Congress, he exposed militarism as the strongest bastion of capitalism, and on behalf of the aspirations of the revolutionary youth, he demanded the establishment of a united social-democratic youth organization, which was later gradually established. At the Jena Party Congress in 1905, he refuted the fallacy of revisionists against the general strike and declared the League general strike "a special and proletarian means of struggle in all fields of class struggle." He also enthusiastically congratulated the Russian Revolution of 1905. With the support of the Social Democrats, the "German Young Workers' Union House" was established in February 1906, and its own official newspaper "Young Guard" was founded. At the first plenary meeting held by the German Young Workers' Federation, Ka Liebknecht gave a report focusing on the struggle against militarism, mobilizing the revolutionary youth to fight resolutely against militarism. In 1906, he published the article "Sending Young Conscripts" in the seventh issue of the newspaper "Young Guards", which sharply exposed the nature of the capitalist army and pointed out that they would suffer all kinds of sufferings and restrictions in the army; Under the banner of "defending the motherland", the bourgeoisie forced them into the army. The so-called "defending the motherland" means the aggression and plunder of China and Africa. He asked the young people in the army to deeply understand the reactionary and decadent nature of militarism. The same year!, At the Mannheim Congress of the German Party, he exposed the reactionary policy of the German government deliberately helping the Tsar government to suppress the revolution, and called on the German proletariat to learn from the example of the Russian proletariat in its own struggle.
