The Pennsic War is an annual American medieval and Renaissance camping event held by the Society for Creative Anachronism (SCA), a "war" between two large regional SCA groups: the Kingdom of the East and the Middle Kingdom. It is the single largest annual SCA event, with more than 10,000 people attending each year, from as far as China, South Korea, Sweden, Germany, France, Italy, Greece, and Australia. Pennsic is held in late summer and lasts for 17 days (begins on a Friday, ends on the third Sunday). The event centers on pre-17th century history and culture with all campers dressing in historically relevant clothing. The winners of the battles and other activities receive war points, and the Kingdom with the most war points wins that Pennsic. The Pennsic War uses numbers to identify each war rather than the year it was held, so the 2019 event was known as "Pennsic War 48", there having been 47 previous events. Due to the COVID-19 pandemic, no Pennsic event was held in 2020 or 2021, and so the 2022 event is known as "Pennsic War 49".
