Kingdom of Lochac
When enough SCA groups in a region have enough members, and all those members want to become a kingdom, they can ask to become one. This happened to Australia in July 2002. The Kingdom of Lochac represents the conglomeration of all SCA groups in Australia and New Zealand (as of Lochac May Crown, 2003), formerly a part of the Kingdom of Caid.
During May and November there is a Crown tournament to choose a new king.
