According to the Communist Manifesto, what would finally happen to the Bourgeoisie?

Marx believed that capitalism contained the seeds of its own destruction. He described how the wealth of the bourgeoisie depended on the work of the proletariat. Therefore, capitalism requires an underclass. But Marx predicted that the continued exploitation of this underclass would create great resentment. Eventually the proletariat would lead a revolution against the bourgeoisie. The final struggle would lead to the overthrow of capitalism and its supporters. Marx wrote that modern bourgeois society 'is like the sorcerer, who is no longer able to control the powers of the nether world whom he has called up by his spells.'
