Diplomacy is a strategic board game created by Allan B. Calhamer in 1954 and released commercially in 1959. Its main distinctions from most board wargames are its negotiation phases and the absence of dice and other game elements that produce random effects. Set in Europe before the beginning of World War I, Diplomacy is played by two to seven players, each controlling the armed forces of a major European power. Each player aims to move his or her few starting units and defeat those of others to win possession of a majority of strategic cities and provinces marked as "supply centers" on the map; these supply centers allow players who control them to produce more units.Diplomacy is a strategic board game created by Allan B.
