The Historical Miniatures Gaming Society, Inc. (HMGS, Inc.) promotes the study of military history through the hobby of historical tabletop miniature wargaming as a registered non-profit 501(c)3 charitable educational membership organization. The association was incorporated in the state of Maryland in July 1986.
HMGS, Inc. has over 2,000 members worldwide. HMGS, Inc. sponsors three major gaming conventions yearly, Historicon, Cold Wars, and Fall-In!, as well as special events and seminars by distinguished historians. Each convention is dedicated to providing the best miniature wargames featuring historical scenarios. There is also a large vendor hall where attendees may purchase hobby and gaming materials and supplies. Each convention features more than 500 events, a flea market called "Wally's Basement" after founder Walter Simon, a seminar series, painting contest, and Paint'N'Take. The conventions also offers classes dedicated to teaching hobby skills like painting and sculpting from beginner to advanced levels at their Hobby University. Cold Wars is located in Lancaster, Pennsylvania and happens in March every year. Historicon takes place in July, is the largest show and is located in Fredericksburg, Virginia. Fall-In! occurs in November in Lancaster, Pennsylvania. Members of HMGS, Inc. get discounts to the conventions, an electronic newsletter and an online member community to share history studies. They have an active social media presence on Facebook, Twitter and Pinterest.
There is a loose federation of other organizations using the name Historical Miniatures Gaming Society - some using the term "chapter" but in fact there is no chartering national organization and no legal/formal connection between the various groups. HMGS, Inc. is the original and largest group.
