Anarcho-syndicalism is a political philosophy and anarchist school of thought that views revolutionary industrial unionism or syndicalism as a method for workers in capitalist society to gain control of an economy and thus control influence in broader society. The end goal of syndicalism is to abolish the wage system, regarding it as wage slavery. Anarcho-syndicalist theory generally focuses on the labour movement. Reflecting the anarchist philosophy from which it draws its primary inspiration, anarcho-syndicalism is centred on the idea that power corrupts and that any hierarchy that cannot be ethically justified must be dismantled. The basic principles of anarcho-syndicalism are solidarity, direct action (action undertaken without the intervention of third parties such as politicians, bureaucrats and arbitrators), and workers' self-management. Anarcho-syndicalists believe their economic theories constitute a strategy for facilitating proletarian self-activity and creating an alternative cooperative economic system with democratic values and production centred on meeting human needs. Anarcho-syndicalists perceive the primary purpose of the state as the defence of private property in the forms of capital goods and thereby of economic, social and political privilege. In maintaining this status quo, the state denies most of its citizens the ability to enjoy material independence and the social autonomy that springs from it. The roots of anarcho-syndicalism lie in the anarchist faction of the International Workingmen's Association (IWA), which upheld the central role of trade unions in the class struggle and called for a general strike to replace the state with a free association of producers. This was in opposition to the Marxist faction, which proposed the seizure of state power by a political party. The IWA's largest section was the Spanish Regional Federation (FRE), which adopted the anarchist platform of revolutionary trade unionism and organised itself according to a structure that anticipated syndicalism.
