Due to his political publications, Marx became stateless and lived in exile with his wife and children in London for decades, where he continued to develop his thought in collaboration with German thinker Friedrich Engels and publish his writings, researching in the reading room of the British Museum.
Karena publikasi politiknya, Marx menjadi tak bernegara dan tinggal dalam pengasingan di London, dimana ia tetap mengembangkan pemikirannya dalam kolaborasi dengan pemikir Jerman Friedrich Engels dan menerbitkan tulisan-tulisannya, melakukan riset di ruang baca British Museum.
