Marxist theory critiques liberal democracy for focusing solely on formal political equality while ignoring substantive economic inequality. It argues that true democracy cannot exist without the socialization of the means of production and the guarantee of economic rights. By prioritizing the material conditions of the working class, Marxist theory seeks to dismantle class-based exploitation, viewing economic liberation as the essential prerequisite for genuine political participation and social justice.

Marxist historiography critiques traditional history for focusing almost exclusively on the actions of elites, monarchs, and ruling classes. Marx argued that such historical narratives were designed to legitimize the status quo and glorify the ruling order, while systematically ignoring the material conditions and the struggles of the working masses, which he believed were the true drivers of historical change.

Marxian theory views representative parliaments as instruments of the 'bourgeois state,' designed to maintain capitalist control rather than represent the true interests of the proletariat. Marxian democracy envisions a transition toward a stateless, classless society where the means of production are collectively managed. Therefore, reliance on traditional representative parliamentary structures is seen as a feature of liberal democracy, not the revolutionary model proposed by Marx.

While both ideologies criticize capitalism and the state, they diverge on the root causes of societal problems. Marxism posits that economic class struggle is the primary driver of history and social evil, whereas Anarchism identifies the existence of authority and the state itself as the fundamental source of oppression and corruption in human society.

In 'The Communist Manifesto', Marx and Engels famously characterize the modern state as 'a committee for managing the common affairs of the whole bourgeoisie.' This definition underscores their belief that state institutions, laws, and policies are structured to facilitate the interests of the capitalist class, thereby reinforcing the exploitation of the proletariat and maintaining the existing economic hierarchy.

This famous opening line appears in 'The Communist Manifesto,' written by Karl Marx and Friedrich Engels in 1848. The text serves as a foundational document for communist ideology, arguing that social change is driven by the conflict between opposing classes—specifically the bourgeoisie and the proletariat. By framing history through the lens of class struggle, Marx and Engels provided a framework for understanding the evolution of political and economic systems.

Socialist theory, particularly in its Marxist tradition, generally views the state as an instrument of class rule rather than a neutral means to an end. The idea that the state is a 'means to an end' is more characteristic of liberal or pluralist theories, whereas socialists typically argue the state must be transformed or abolished to achieve true social equality.

This statement is the foundational thesis of the 'Communist Manifesto', authored by Karl Marx and Friedrich Engels. It serves as the starting point for their analysis of history, suggesting that all social change is rooted in the struggle between those who control the means of production and those who do not.

Communist theory posits that traditional liberal constitutionalism is a tool of the bourgeoisie. Instead, it emphasizes the role of the vanguard party and the implementation of communist ideology to restructure society. The provided answer suggests international cooperation or ideological alignment as the path forward, though this reflects a specific interpretation of how socialist states view the transition toward their version of governance.

In Marxist theory, the statement that 'History progresses due to class conflict' is actually a core tenet of Historical Materialism. Therefore, labeling it as incorrect is factually inconsistent with Marx's writings. This question appears to contain a logical error regarding the identification of Marxist principles.
