availability and funding for the event, such as the Battle of Bannockburn. Belgium has at least two dozen separate groups of medieval reenactors, including the Order of the Hagelanders, the Gentsche Ghesellen and the Gruuthuse Household serving Lewis de Bruges, lord of Gruuthuse. The open air museum Middelaldercentret uses living history and historical reenactment to portrait a part of a small Danish merchant town. Several reenactment groups exists in Denmark which are doing medieval reenactment at markets around the country. In France there is an annual reenactment of the Battle of Agincourt representing a battle of the Hundred Years War. In Germany medieval reenactment is usually associated with living history and renaissance fairs and festivals as e.g. the Peter and Paul festival in Bretten. or the Schloss Kaltenberg knights tournament. In the past few years combat reenactment has gained some ground as well. A few groups are training historical combat such as longsword dueling and dussack fighting at universities, but the majority of combat reenactment groups are battlefield reenactment groups, some of which have become isolated to some degree because of a strong focus on authenticity (some groups refuse to fight groups representing different or wider periods, even if the combat practices would be entirely compatible otherwise). In general, the specific German approach of Authenticity (reenactment) is less about replaying a certain event, but to allow an immersion in a certain era. Historic city festivals and events are quite important to build up local communities and contribute to the self-image of municipalities. Events in monuments or on historical sites are less about the events related to them but as mere staffage for the immersion experience. Among many battlefield reenactors in Germany, the Codex Belli has become a de facto standard. 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 arrow heads and an overall higher acceptance of the risk of injury posed by these dangers. This more risky, although more realistic, form of reenactment is apparently also practiced in former East Germany. In Poland, the Battle of Grunwald reenactment every year on 15 July is the best known and attracts participants and visitors from many other countries. It is associated with living history and a medieval fair. In Sweden there are many different "medieval markets". The largest is the one in Gotland.
