Karl Marx Biography and Synopsis of Views Karl Heinrich Marx was born on May 5, 1818, in the city of Trier in Prussia, now, Germany. He was one of seven children of Jewish Parents. His father was fairly liberal, taking part in demonstrations for a constitution for Prussia and reading such authors as Voltaire and Kant, known for their social commentary. His mother, Henrietta, was originally from Holland and never became a German at heart, not even learning to speak the language properly. Shortly before Karl Marx was born, his father converted the family to the Evangelical Established Church, Karl being baptized at the age of six.
