Marxism is a scientific worldview upholding the fundamental interests of the working class. The marxist scientific worldview emerged in the 1840s, when the antagonistic contradictions of capitalist society were sharply manifested, and the working class as an independent political force emerged in Europe
Marx and Engels were the developers of the scientific worldview of the working class, the program, strategy and tactics of its revolutionary struggle. They critically rethought and creatively reworked the achievements of the previous scientific and social thought of mankind, summarized the experience of the class struggle and revolutionary movement of the working masses.
The most important theoretical sources of Marxism were classical German philosophy, English political economy and French utopian socialism. Marxism took a fundamentally new approach to solving practical and theoretical problems and gave a scientific answer to the main questions posed by the course of social development and, above all, by the development of capitalism and the labor movement; it overcame the idealism and anti-historical, contemplative nature typical of previous social thought.
