The history of the board game Monopoly can be traced back to the early 20th century. The earliest known design was by the American Elizabeth Magie created in 1903. A series of board games were developed from 1906 through the 1930s that involved the buying and selling of land and the development of that land. By 1934, a board game had been created much like the version of Monopoly sold by Parker Brothers and its parent companies through the rest of the 20th century, and into the 21st. Several people, mostly in the Midwestern United States and near the East Coast, contributed to the game’s design and evolution.
