The Historical Miniatures Gaming Society (or HMGS) promotes the hobby of historical miniature wargaming as a registered non-profit charitable and educational foundation. The organization consists of a loose-knit group of regional chapters, primarily located throughout the United States.
The largest chapter, East, has over 2,000 members worldwide, although the vast majority are from the East Coast of the United States. HMGS East sponsors three major gaming conventions (Historicon, Cold Wars, and Fall In!), as well as special events and seminars by distinguished historians.
The HMGS-Great Lakes chapter runs the historicals events at the annual Origins Game Fair in Columbus, Ohio.
The HMGS-South chapter is also quite active, hosting two large gaming conventions in Florida.
