Friedrich Engels, having decided to return to Germany in 1844, stops in Paris to meet Karl Marx, with whom he had had an earlier correspondence.

Marx had been living in Paris since late October 1843, after the Rheinische Zeitung was banned in March 1843 by Prussian governmental authorities.

Prior to meeting Marx, Engels had become established as a fully developed materialist and scientific socialist, independent of Marx's philosophical development.

In Paris, Marx is publishing the Deutsch–Französische Jahrbücher.

Engels meets Marx for a second time at the Café de la Régence on the Place du Palais, August 28, 1844.

The two will quickly become close friends and will remain so their entire lives.

Marx has read and is impressed by Engels's articles on The Condition of the Working Class in England.

Marx will adopt Engels's idea that the working class will lead the revolution against the bourgeoisie as society advances toward socialism, and will incorporate this as part of his own philosophy.
