The use of the word royalty, as fee to a proprietor for the exploitation of a work or property, derives from the period when the sovereign assumed title to all wealth of the realm. It was the struggle for freedom from these encroachments of the state that chiefly marked the Nineteenth Century, and established everywhere constitutional regimes of limited authority. In the Twentieth Century, however, we have witnessed a gradual and almost unrestricted movement back to state authoritarianism, primarily in the economic sphere, accompanied by the spread of state monopoly and intervention.
