Assizes of Jerusalem

The Assizes of Jerusalem are a collection of medieval legal treatises written in Old French recording the law of the crusader kingdoms of Jerusalem and Cyprus, compiled mainly in the 13th century even though the legal system of the Kingdom of Jerusalem dated back to its founding in 1099. The surviving collection includes the Livre au Roi, a treatise by Philip of Novara, a lengthy legal code by John of Ibelin, and rules for the burgess court that heard cases involving commoners. Together these works address feudal relations, court procedure, vassal obligations and succession, and form the largest surviving collection of medieval law written in a European founded state of that period.
