* The Communist Manifesto (1848): Written with Friedrich Engels, this short but powerful pamphlet outlines the principles of communism, criticizes capitalism, and calls for a revolution of the working class. It's considered one of the most influential political texts ever written.
* Das Kapital (Capital) (1867): This multi-volume work is Marx's most comprehensive analysis of capitalism. It examines the economic, social, and political structures of capitalist society, critiques its inherent contradictions, and predicts its eventual demise.
While these are his most famous, Marx also wrote extensively on other topics, including:
* The German Ideology (1845): A critique of Hegelian philosophy and a development of historical materialism.
* Critique of the Gotha Program (1875): An analysis of the political program of the German Social Democratic Party.
* Economic and Philosophic Manuscripts of 1844: A collection of early writings on alienation and the nature of human labor.
It's important to note that Marx's works are complex and have been interpreted in various ways throughout history. They continue to be studied and debated in academic circles and remain relevant in understanding contemporary political and economic issues.
