Meaning: The quote "Class struggle: external peace, international solidarity, peace among peoples. This is the sacred slogan of international socialist democracy that liberates nations." is a powerful statement by Karl Liebknecht, a prominent German socialist politician and anti-war activist. This quote encapsulates the core principles of international socialist democracy, emphasizing the interconnectedness of class struggle, external peace, international solidarity, and peace among peoples.

Karl Liebknecht was a key figure in the early 20th-century socialist movement in Germany and a vocal critic of the capitalist system and imperialist wars. He was a co-founder of the Spartacus League, which later became the Communist Party of Germany. Throughout his political career, Liebknecht advocated for the rights of the working class, fought against militarism, and promoted international solidarity among oppressed peoples.

The concept of "class struggle" is central to Marxist theory, which posits that society is divided into conflicting classes with opposing interests: the bourgeoisie (the capitalist class) and the proletariat (the working class). The quote underscores the idea that the struggle for social and economic justice is inherently linked to the pursuit of external peace and international solidarity. In other words, the liberation of nations and the achievement of peace are intricately tied to the resolution of class-based conflicts and the dismantling of oppressive systems.

Furthermore, the mention of "international socialist democracy" reflects Liebknecht's belief in a global movement towards socialist ideals, emphasizing the need for democratic governance and social ownership of the means of production on an international scale. This vision of international solidarity and cooperation among socialist movements aligns with the broader goals of the socialist and communist movements of the time, which sought to transcend national boundaries and unite the working class across countries.

The notion of "peace among peoples" in Liebknecht's quote is particularly significant in the context of the era in which he lived. The early 20th century was marked by devastating conflicts, including World War I, which had a profound impact on European societies and led to widespread suffering and loss. Liebknecht was an outspoken opponent of this war and was one of the few voices in the German Reichstag to vote against war credits, a courageous act that landed him in prison.

By emphasizing the importance of peace among peoples, Liebknecht not only condemned the destructive nature of war but also envisioned a world in which nations would coexist peacefully, free from the grip of imperialist aggression and militarism. His advocacy for peace and international solidarity resonated with many who were disillusioned by the catastrophic consequences of war and sought an alternative vision for a more just and equitable world.

In conclusion, Karl Liebknecht's quote encapsulates the core principles of international socialist democracy, highlighting the interconnectedness of class struggle, external peace, international solidarity, and peace among peoples. His vision of a world liberated from oppression, inequality, and war continues to inspire and resonate with those who strive for social justice and global solidarity.
