The Society for Creative Anachronism (SCA), founded in California in 1966, is an international organization of medieval reenactors engaged in learning and teaching western martial arts through a combination of armored combat with rattan wasters, rapier fencing and archery, as well as arts and sciences of the Middle Ages and Renaissance (c. 500-1550). Years in the SCA are often reckoned in years of the Society, beginning with May 1966, for ceremonial purposes. So May 1966 to April 1967 was A.S. (Anno Societatis) I, and May 2013 to April 2014 is A.S. XLVIII.
