Friedrich Engels

Friedrich Engels (1820-1895) was a German theorist, political organizer, and collaborator of Karl Marx. Beyond co-authoring foundational works, he wrote on political economy, class struggle, and the historical development of family and state forms, helping systematize historical materialism for wider socialist movements.

Within materialist psychology, Engels is important because he insisted that human thought and culture arise from labor, social relations, and changing material conditions. That orientation supports a psychology that treats consciousness as historically produced rather than as an isolated inner essence.
