Pierre-Joseph Proudhon, French economist and politician (died 1865)

Pierre-Joseph Proudhon was a French anarchist, socialist, philosopher, and economist who founded mutualist philosophy and is considered by many to be the "father of anarchism". He was the first person to call himself an anarchist, and is widely regarded as one of anarchism's most influential theorists. Proudhon became a member of the French Parliament after the Revolution of 1848, whereafter he referred to himself as a federalist. Proudhon described the liberty he pursued as the synthesis of community and individualism. Some consider his mutualism to be part of individualist anarchism while others regard it to be part of social anarchism.
