 In recent history, libertarian socialists have repeatedly formed temporary alliances with Marxist–Leninist groups for the purposes of protest against institutions they both reject.Part of this antagonism can be traced to the International Workingmen's Association, the First International, a congress of radical workers, where Mikhail Bakunin, who was fairly representative of anarchist views; and Karl Marx, whom anarchists accused of being an "authoritarian", came into conflict on various issues.Bakunin's viewpoint on the illegitimacy of the state as an institution and the role of electoral politics was starkly counterposed to Marx's views in the First International.
