Karl Marx was born in 1818, in the Rhenish city of Trier, the son of a successful lawyer. He studied law and philosophy at the universities of Bonn and Berlin, completing his doctorate in 1841. In Paris three years later, Marx was introduced to the study of political economy by a former fellow student, Frederick Engels. In 1848 they collaborated in writing
The Communist Manifesto. Expelled from Prussia in the same year, Marx took up residence first in Paris and then in London where, in 1867 he published his magnum opus
Capital. A co-founder of the International Workingmen's Association in 1864, Marx died in London in 1883.
