Individualist anarchism in Europe proceeded from the roots laid by William Godwin and soon expanded and diversified through Europe, incorporating influences from individualist anarchism in the United States. Individualist anarchism is a tradition of thought within the anarchist movement that emphasize the individual and his or her will over external determinants such as groups, society, traditions, and ideological systems. While most American individualist anarchists advocate mutualism, a libertarian socialist form of market socialism, or a free-market socialist form of classical economics, European individualist anarchists are pluralists who advocate anarchism without adjectives and synthesis anarchism, ranging from anarcho-communist to mutualist economic types.

Individualist anarchism in the United States was strongly influenced by Benjamin Tucker, Josiah Warren, Ralph Waldo Emerson, Lysander Spooner, Pierre-Joseph Proudhon, Max Stirner, Herbert Spencer and Henry David Thoreau. Other important individualist anarchists in the United States were Stephen Pearl Andrews, William Batchelder Greene, Ezra Heywood, M. E. Lazarus, John Beverley Robinson, James L. Walker, Joseph Labadie, Steven Byington and Laurance Labadie.
