During Engels' short stay in Paris in 1844, Marx suggested the two of them should write a critique of the rage of their day, the Young Hegelians. In the doing was born the first joint writing project between the two men — and a life-long association that would change the world.
At the end of August, 1844, Engels passed through Paris, en route to his employment in Manchester, England, from visiting his family in Barmen (Germany). During 10 days in the French capital, he met Marx (for the second time).
After talking, they began drawing up plans for a book about the Young Hegelian trend of thought very popular in academic circles. Agreeing to co-author the Foreword, they divided up the other sections. Engels finished his assigned chapters before leaving Paris. Marx had the larger share of work, and he completed it by the end of November 1844. (Marx would draw from his Economic and Philosophical Manuscripts, on which he'd been working the spring and summer of 1844.)
