In Sweden there are many different "medieval markets". The largest is the one in Gotland. In Szeklerland, Transylvania are many Hun, szekler knight, early Hungarian and hussar reenactment groups and camps.
Groups from Central Europe, especially Hungary, are rumored to practice much more dangerous forms of battlefield reenactment, sometimes with sharp edges and points as well as metal arrowheads etc.
A medieval reenactment is a form of historical reenactment that focuses on re-enacting European history in the period from the fall of Rome to about the end of the 15th century. The 2nd is the Middle Ages.
