HISTORY OF MONOPOLY
The history of Monopoly can be traced back to 1904, when an American woman named Elizabeth Magie Phillips created a game through which she hoped to be able to teach the single tax theory of economist Henry George (it was intended to illustrate the negative aspects of concentrating land in private monopolies). Her game, The Landlord's Game, was commercially published in 1923. It was one of the first board games to use a continuous path, without clearly defined start and end spaces on its board.
In the 1932, Daniel Layman, produced a version of the board based on the streets of his home city of Indianapolis and introduced Chance and Community Chest cards. This he sold under the name The Fascinating Game of Finance.
But it is Charles Darrow who is accredited with first publishing the actual game of Monopoly in 1934. After losing his job at a sales company following the Stock Market Crash of 1929 and seeing his neighbours and acquaintances play a home-made board game in which the object was to buy and sell property, he decided to publish his own version of the game.
