With the development of capitalist economy and society, the contradictions and ugliness of capitalist society are increasingly exposed. From 65438 to 0825, the first economic crisis broke out in Britain. 1837 A greater economic crisis broke out. The direct victims of this crisis are still the working people. Therefore, with the development of capitalism, the class struggle between the proletariat and the bourgeoisie has become increasingly acute. At the same time, the emergence of large industries has strengthened the organization of the working class. The development of transportation industry is conducive to the contact of workers in various regions. The proletariat in western Europe began to organize, gradually moving from individual spontaneous struggle to organized struggle, from simple economic struggle to political struggle. 183 1 and 1834 Two armed uprisings of Lyon workers broke out in France. The British constitutional movement from 1836 to 1848 was "the first extensive, truly mass and political proletarian revolutionary movement". 1844, the textile workers in Silesia, Germany, rose in arms, sharply declaring their opposition to the private ownership society and realizing the essence of the proletariat.
In these three labor movements, the proletariat constantly summed up the lessons of failure, and not only established trade union organizations, but also began to establish political organizations. The proletariat has become "the third fighter fighting for rule". In other words, the proletariat, as an independent political force, has begun to step onto the stage of human history.
