Three more co-founders are mentioned by Douglas Martin in the New York Times Obituaries of August 3 , 2001 ( p.A23 , " Poul Anderson , Science Fiction Novelist , Dies at 74 " ) : " Anderson and Karen Kruse moved to San Francisco and were married ... They and their daughter , Astrid ... founded the Society for Creative Anachronism , which ... has spread nationwide . " In 1968 , Bradley moved to Staten Island , New York and founded the Kingdom of the East , holding a tournament that summer to determine the first Eastern King of the SCA . That September , a tournament was held at the 26th World Science Fiction Convention , which was in Berkeley that year . The SCA had produced a book for the convention called '' A Handbook for the Current Middle Ages '' , which was a how-to book for people wanting to start their own SCA chapters . Convention goers purchased the book and the idea spread . Soon , other local chapters began to form . In October 1968 , the SCA was incorporated as a 501 ( c ) ( 3 ) non-profit corporation in California . By the end of 1969 , the SCA 's three original kingdoms had been established : West Kingdom , East , and Middle . All SCA kingdoms trace their roots to these original three . The number of SCA kingdoms has continued to grow by the expansion and division of existing kingdoms ; for example , the kingdoms now called the Outlands , Artemisia , Ansteorra , Gleann Abhann , Meridies , and Trimaris all are made up of lands originally belonging to the fourth kingdom , Atenveldt , which began as a branch of the West Kingdom
