 Magie, a follower of Henry George, originally intended "The Landlord's Game" to illustrate the economic consequences of Ricardo's Law of Economic rent and the Georgist concepts of economic privilege and land value taxation.A series of board games was developed from 1906 through the 1930s that involved the buying and selling of land and the development of that land.By 1933, a board game had been created much like the modern version of "Monopoly" sold by Parker Brothers and its related companies through the rest of the 20th century, and into the 21st.
