De Leonism: De Leonism, occasionally known as Marxism–De Leonism, is a form of syndicalist Marxism developed by the American activist Daniel De Leon.  De Leon was an early leader of the first United States socialist political party, the Socialist Labor Party of America.  De Leon combined the rising theories of syndicalism in his time with orthodox Marxism.  According to De Leonist theory, militant industrial unions are the vehicle of class struggle.  Industrial Unions serving the interests of the proletariat (working class) will bring about the change needed to establish a socialist system.  While sharing some characteristics of anarcho-syndicalism (the management of workplaces through unions), and with the SLP being a member of the predominantly anarcho-syndicalist Industrial Workers of the World (IWW), De Leonism actually differs from it in that he and the modern SLP still believe in the necessity of a central government to coordinate production, as well as in the use of a revolutionary political party in addition to union action to achieve its goals.
