According to Karl Marx, is part of a collective process in which the proletariat comes to identify the bourgeoisie as the source of its oppression.

Revolution.

Explanation:

The proletarian revolution is, in Marxist literature, a violent and class-based political revolution with which the proletarian class sets out to overthrow capitalism and, in the first place, break its institutions. The proletarian revolutions are generally supported by the communists and, albeit with different aims, by the anarchists.

The proletarian revolution is an ineliminable concept of Marxism as a consequence of the impossibility of a reform capable of eliminating the capitalist relations of production within capitalism itself. In Marxist theory the proletarian revolution, to be truly capable of abolishing the capitalist mode of production, must have a strictly internationalist nature, even if the revolutionary process were to begin in the form of national anti-bourgeois revolutions.
