Marx and Engels emphasized in the * * * Declaration that the bourgeoisie, by opening up the world market, makes the production and consumption of all countries in the world. The spiritual products of all ethnic groups become public property. One-sidedness and limitations of a nation are becoming more and more impossible, and various national and local literature forms a kind of world literature.

The declaration expounded the theory of scientific socialism for the first time and pointed out that the communist movement has become an irresistible historical trend.

The basic principle that constitutes the core of the Declaration is that the main modes of production and exchange in each historical era and the inevitable social structure are the basis for the establishment of the political and spiritual history of that era, and only from this basis can history be explained.

The manifesto uses dialectical materialism and historical materialism to analyze the contradiction between productive forces and relations of production, economic base and superstructure, the emergence and development of class and class struggle, especially the class struggle in capitalist society, and demonstrates the objective law that capitalism will inevitably perish and socialism will inevitably win. This is the world historical mission shouldered by the proletariat as the grave digger of capitalism.

* * * The manifesto publicly announced that the bourgeois rule must be overthrown by revolutionary violence, and the "political rule" of the proletariat was established, expressing the idea of replacing the bourgeois dictatorship with proletarian dictatorship.

In the declaration of "* * *", Marx put family relations in capitalist relations, pointing out that capitalism has turned family relations into money relations, and in this relationship, women are in the position of pure production tools. Therefore, women's liberation, as far as women's own liberation is concerned, is to make women no longer in the position of simple production tools, enjoy equal social rights with men, and become all-round and free-developing people. Therefore, private ownership must be eliminated.

The "Declaration" also pointed out that after the proletariat seized power, it must gradually carry out social transformation on the basis of vigorously developing productive forces and eliminate the conditions for class opposition and class itself to exist.

When the private ownership of the means of production and the class are eliminated, the country will perish. By that time, instead of the class and class-antagonistic bourgeois society, it is such a consortium, in which everyone's free development is the condition for everyone's free development, that is, to enter a communist society.
