Castle Greyhawk was never published for public play, instead with many of the elements of Gygax's original campaign becoming the seed for other adventures. Development history Early development In the late 1960s, Gary Gygax, a military history buff and pulp fantasy fan, was a central, founding figure in the Castle & Crusade Society. The C&C Society, as it was known, served enthusiasts of miniature wargaming in the Middle Ages and published an occasional newsletter known as the Domesday Book. Following up on a promise he made in Domesday Book #5, Gygax presented the "Great Kingdom" map c. June 1971 in Domesday #9, to be used as a game setting for the Society. Members thereafter began claiming territories, including member Dave Arneson, who was an officer of the organization, and frequent contributor to the newsletter.

Lee Tucker dismissed it, and me. Mike Reese and Jeff Perren were not captivated by giants hurling boulders and dragons breathing fire and lightning bolts, nor did wizards with spells, heroes and superheroes with magic armor and swords prove compelling to them." To this end, Gygax created a fantasy supplement for the Chainmail ruleset for medieval miniatures that he was co-writing with Jeff Perren. Released in the late spring of 1971, this booklet included rules for fantasy monsters, wizards and magical weapons. Around the same time, in Minneapolis–St. Paul, Dave Arneson, impressed by the "Braunstein" role-playing games of fellow wargamer David Wesely, developed the Barony of Blackmoor as a setting for Braunstein style games. Arneson based his game around the village, castle and dungeons of Blackmoor. The castle itself was represented on the table by an actual
