A land monopoly occurs when an entity or a class is able to corner the market on land. According to Winston Churchill, "Land monopoly is not the only monopoly, but it is by far the greatest of monopolies – it is a perpetual monopoly, and it is the mother of all other forms of monopoly." According to anarcho-capitalist Murray Rothbard, "Land monopoly is far more widespread in the modern world than most people – especially most Americans – believe. In the undeveloped world, especially in Asia, the Middle East, and Latin America, feudal landholding is a crucial social and economic problem – with or without quasi-serf impositions on the persons of the peasantry." Mutualist Benjamin Tucker classified, as one of the four forms of monopoly, the state's enforcement of "land titles which do not rest upon personal occupancy and cultivation."
There are numerous mechanisms of ameliorating land monopolization.
