Explain Karl Marx's conception of transition from 'class-in- itself' to 'class-for-itself'.

According to marx, under capitalist system, Capitalists are the dominating class who exploits the working class.

when these working class are not aware about mechanism of their exploitation and the exploiter, But they share the common and same Control over FoP. This is called class in itself.

The capitalist class don't use naked for exploitation but use Coercion in an hidden manner using economic instruments and by infusing false ideology in super structure.

With globalisation and intensed exploitation of workers under "general law of capitalist accumulation", workers get awareness about their common enemy. This leads to homogenisation of workers and gives birth to class for itself. This "Class for itself" revolt against Capitalist system and socialism and Communism will usher finally.
