I am doing research on board games for week 6 and the one that I am doing is Monoply. So here is the when Monoply was invented. The earliest known version of Monopoly, known as The Landlord’s Game, was designed by an American, Elizabeth Magie, and first patented in 1904 but existed as early as 1902. Here is the where Monoply was inveted. Several people, mostly in the Midwestern United States and near the East Coast, contributed to the game’s design and evolution. Now here is the why Monoply was inveted. The history of Monopoly can be traced back to 1903, when American Elizabeth (Lizzie) J. Magie Phillips created a game through which she hoped to be able to explain the single tax theory of Henry George.
I got this information from http://en.m.wikipedia.org/wiki/Monopoly_(game)
