Engels' interpretation proved to be extremely influential with British historians of the Industrial Revolution. He focused on both the workers' wages and their living conditions. He argued that the industrial workers had lower incomes than their pre-industrial peers and they lived in more unhealthy and unpleasant environments. This proved to be a very wide-ranging critique of industrialisation and one that was echoed by many of the Marxist historians who studied the industrial revolution in the 20th century.
Originally addressed to a German audience, the book is considered by many to be a classic account of the universal condition of the industrial working class during its time. The eldest son of a successful German textile industrialist, Engels became involved in radical journalism in his youth. Sent to England, what he saw there made him even more radical. About this time he formed his lifelong intellectual partnership with Karl Marx.
