Karl Marx is born in Trier, Germany. One of the most important figures in the development of both economic and political philosophy in both the 19th and 20th centuries, Karl Marx will responsible for the revolutionary idea of communism and some of the most prescient critiques of modern industrial capitalism.
With fellow German and socialist Friedrich Engels, Karl Marx will write some of the most widely-read political and economic works of the modern era. The ideas which Karl Marx develops will acquire the label "Marxism," but Marx will not come up with them on his own — Friedrich Engels will be crucial to Marx both personally and professionally. If not for Engels' constant and selfless financial assistance, Marx would not only be unable to complete most of his major works, but might succumb to hunger and malnutrition.
