The Society for Creative Anachronism, Inc. was created in 1966 because of a graduation party hosted by UC Berkeley medieval studies graduate and author Diana Paxton. The society is an international non-profit educational corporation and living history organization with the goal to study and recreate Medieval European cultures and history before the 17th century. Events held includes tournaments, royal courts, feasts, and dancing. They also include educational and practical activities revolving around the ancient arts and skills of that time period. Since its start it has expanded to over 30,000 paid members in their 60,000 total number of participants. It divides itself into different administrative regions called kingdoms, with smaller regions within it. Then within those kingdoms and local groups, there is a standard board of officers with titles loosely based off medieval titles. The society incorporated itself as non-profit in California, with its headquarters in Milpitas.
