Codex Belli is the name of a set of rules for medieval combat reenactment first issued in 1999 and then revised by the German umbrella group Kämpferliste in 2002. The Codex Belli, literally Laws of Battle, are a ruleset for unchoreographed semi-contact combat with medieval reenactment weapons, which differ most notably from realistic replicas in that they have rounded edges and points. The goal of this ruleset was to create a common standard for safe fighting practices as lower-scale reenactment events grew larger and a trust-based system became insufficient with the increasing number of reenactors involved.
