Utopian socialism is the term often used to describe the first current of modern socialism and socialist thought as exemplified by the work of Henri de Saint-Simon, Charles Fourier, Étienne Cabet, and Robert Owen. Utopian socialism is often described as the presentation of visions and outlines for imaginary or futuristic ideal societies, with positive ideals being the main reason for moving society in such a direction. Later socialists and critics of utopian socialism viewed utopian socialism as not being grounded in actual material conditions of existing society. These visions of ideal societies competed with revolutionary and social democratic movements.

Socialism is an economic and political philosophy encompassing diverse economic and social systems characterised by social ownership of the means of production, as opposed to private ownership. It describes the economic, political, and social theories and movements associated with the implementation of such systems. Social ownership can take various forms, including public, community, collective, cooperative, or employee. Traditionally, socialism is on the left wing of the political spectrum. Types of socialism vary based on the role of markets and planning in resource allocation, and the structure of management in organizations.
