Who invented the game of monopoly and in what year was it introduced?

The game of Monopoly was invented by Charles Darrow in 1935.

However, it's important to note that the game was actually based on an earlier game called "The Landlord's Game", which was created by Elizabeth Magie in 1903. Magie designed her game to be a teaching tool about the evils of monopolies and land ownership.

Darrow modified Magie's game, adding elements like the Chance and Community Chest cards, and eventually sold it to Parker Brothers in 1935.
