The SCA or, the Society for Creative Anachronism is a worldwide club, for people who attempt to recreate the middle ages from 600 AD to 1600 AD.
You can have a ‘pretend personality’ (your persona) who comes from anywhere in the world during whichever era you choose from our one thousand year span.
We like to hold events where we get together and take great pains to have a real Medieval atmosphere. Electronic devices are to be kept hidden when possible, the music and food will be as truly medieval as we can manage. You are requested to at least make an effort at looking authentic. Your clothes are called ‘garb’.
The SCA is a non-profit organization based in California. For more information about their history, please go here: http://www.sca.org/
