Imperial 1840 is a variant of Avalon Hill/Hasbro's game of Diplomacy by Allan B. Calhamer. It is based on another variant by Michael David Roberts called Imperial. Both variants are global versions of the original game.
Imperial 1840 was actually a beta version and is replaced by Imperial1841 which incorporates changes gleaned from play-testing of Imperial 1840.
