Monopoly is named after the economic concept of monopoly—exclusive control over a commodity or service in a particular market, eliminating competition.
Elizabeth Magie's 1904 The Landlord's Game (Monopoly's direct ancestor) was created to illustrate the dangers of monopolistic land ownership and demonstrate Henry George's single-tax theory. The game showed how rent extraction concentrates wealth and bankrupts tenants.
Charles Darrow's 1933 version (sold to Parker Brothers) stripped the anti-monopolist messaging but kept the core mechanic: acquire dominance, charge rent, drive opponents to ruin. The name remained—ironically celebrating what the original warned against.
The game simulates unregulated capitalism's tendency toward monopoly: early advantages compound, late entrants get crushed, one player ends owning everything. The name isn't decorative—it's the thesis.
