Dungeons & Dragons (DnD) was co-created by Gary Gygax and Dave Arneson in the early 1970s and first published in 1974 by the company TSR (Tactical Studies Rules).

Who Created DnD?

  • The game is credited to two American game designers:
    • Gary Gygax, a passionate tabletop wargamer from Lake Geneva, Wisconsin.
* Dave Arneson, a fellow wargamer whose Blackmoor campaign introduced many early role‑playing ideas.
  • Their collaboration turned miniature wargames into a new kind of fantasy role‑playing experience that became Dungeons & Dragons.

How DnD Started

  • DnD grew out of historical miniatures wargames, especially a ruleset called Chainmail that Gygax helped develop.
  • Arneson experimented with more character‑focused campaigns (like Blackmoor), then brought these ideas to Gygax; together they wrote rules that became the first DnD set.
  • The first edition of Dungeons & Dragons was released in 1974, published by TSR, a company Gygax co‑founded to get the game into print.
