Historical Meaning (OED)
The word "socialism" appeared in English in the 1820s–30s, associated with Robert Owen, the Owenites, and French thinkers like Saint-Simon and Fourier.
The OED historically defined it as a theory or policy advocating community ownership or control of the means of production, capital, land, and property, administered for the benefit of society as a whole. Fundamentally, it was an economic doctrine concerning ownership and control—not a synonym for kindness, public services, or general government assistance.
