The Condition of the Working Class in England is a study of the industrial working class in Victorian England. Engels' first book, it was originally written in German as Die Lage der arbeitenden Klasse in England; an English translation was published in 1885. It was written during Engels' 1842–44 stay in Manchester, the city at the heart of the Industrial Revolution, and compiled from Engels' own observations and detailed contemporary reports. After their first meeting in 1844, Karl Marx read and was profoundly impressed by the book.
