The Barony of the Cleftlands would like to wish the Society for Creative Anachronism Happy 52nd Birthday!
An abridged history from the annuls of Wikipedia:
The SCA’s roots can be traced to a backyard graduation party of a UC Berkeley medieval studies graduate, the author Diana Paxson, in Berkeley, California, on May Day in 1966. The party began with a “Grand Tournament” in which the participants wore helmets, fencing masks, and usually some semblance of a costume, and sparred with each other using weapons such as plywood swords, padded maces, and fencing foils. It ended with a parade down Telegraph Avenue with everyone singing “Greensleeves”. […] The name Berkeley Society for Creative Anachronism was coined […] when the nascent group needed an official name in order to reserve a park for a tournament. “Berkeley” was dropped as the group expanded.
