The Assizes of Jerusalem: The Legal Code of the Crusader States
The Assizes of Jerusalem were the unique legal code of the Kingdom of Jerusalem and the other Crusader States. The modern scholarship on the Assizes is dominated by John La Monte’s Feudal Monarchy in the Latin Kingdom of Jerusalem, 1100 to 1291 (1932), which is now nearly a century old but has not been replaced, and by the more recent work of Iris Shagrir, whose edited collection Crusader and Crusader Law (1997) and follow-up monograph Writing the Crusader Law (2011) have refined the picture considerably. The Assizes were compiled in the 12th and 13th centuries, and they drew on the legal traditions of France, Italy, and the Byzantine Empire. The Assizes were a major contribution to European law, and they have been the subject of intense legal and historical study.

The Origins of the Assizes
The Assizes of Jerusalem were not written down in a single act of legislation, but were compiled over a long period of time. The earliest components of the Assizes date to the early 12th century, when the Kingdom of Jerusalem was still in its infancy. The Assizes were based on the legal traditions of the various regions of France from which the Crusaders came, as well as on the legal traditions of Italy and the Byzantine Empire.
The Assizes were also influenced by the local legal traditions of the Holy Land. The Latin population of the Kingdom was a small minority, and it had to govern a much larger non-Latin population. The legal traditions of the Greek Orthodox Christians, the Syrian Christians, the Jews, and the Muslims were all influential in the development of the Assizes.
The Assizes were probably first written down in the late 12th or early 13th century, when the Kingdom was at the height of its power. The compilation of the Assizes was a major intellectual achievement, and it has been the subject of intense legal and historical study. The most important modern work on the origins of the Assizes is John La Monte’s Feudal Monarchy in the Latin Kingdom of Jerusalem, 1100 to 1291 (1932), which provides a detailed and balanced account of the Assizes’ origins and development.
The Structure of the Assizes
The Assizes of Jerusalem were organized in a number of different sections, each of which dealt with a specific aspect of the legal system. The most important sections were the Assizes of the High Court, the Assizes of the Burgesses, and the Assizes of the Syrian Court. Each of these sections was itself divided into a number of specific Assizes, which dealt with specific legal questions.
The Assizes of the High Court were the most important section, and they dealt with matters of feudal law. They governed the relationship between the king and the barons, the relationship between the barons and their knights, and the relationship between the lords and their peasants. The Assizes of the High Court also dealt with matters of criminal law, including the punishment of crimes and the conduct of trials.
The Assizes of the Burgesses dealt with matters of commercial law, including the regulation of trade, the resolution of commercial disputes, and the protection of property. The Assizes of the Burgesses were based on the legal traditions of the Italian maritime republics, especially Venice and Genoa, and they reflected the importance of commerce to the Kingdom’s economy.
The Assizes of the Syrian Court dealt with matters involving the non-Latin population of the Kingdom. They regulated the relationship between the Latin rulers and their non-Latin subjects, and they provided a framework for the administration of justice in cases involving non-Latin parties. The Assizes of the Syrian Court were a major innovation in medieval law, and they have been the subject of intense legal and historical study.
The High Court of Jerusalem
The Assizes of Jerusalem were administered by a system of courts, with the High Court at the top. The High Court was presided over by the king, and it was attended by the great barons of the Kingdom, the Latin patriarch of Jerusalem, and the masters of the Knights Templar and the Knights Hospitaller. The High Court had jurisdiction over the most important cases, including disputes between the king and the barons, and it served as a court of appeal for the lower courts.
The High Court was the most important political institution of the Kingdom, and it was the site of many of the most important political events of the Kingdom’s history. The High Court was also the source of the Kingdom’s law, and its decisions were considered authoritative for all future cases.
The High Court was supplemented by a number of lower courts, including the courts of the various barons and the courts of the cities. The lower courts had jurisdiction over less important cases, and they were presided over by the barons or the city authorities. The lower courts were bound by the decisions of the High Court, and they applied the Assizes of Jerusalem in their own decisions.
The Significance of the Assizes
The Assizes of Jerusalem were a major contribution to European law. They were among the most sophisticated legal codes of the medieval period, and they have been studied by legal historians for centuries. The Assizes were influential in the development of feudal law and commercial law, and they were widely used in other parts of the Mediterranean.
The Assizes were also significant for the development of the legal traditions of the Crusader States. The Assizes provided a framework for the administration of justice in a complex multicultural society, and they were a major factor in the stability of the Kingdom. The Assizes were also a major expression of the Latin legal tradition in the Eastern Mediterranean, and they have been the subject of intense legal and historical study.
The most important modern work on the Assizes is John La Monte’s Feudal Monarchy in the Latin Kingdom of Jerusalem, 1100 to 1291 (1932), which provides a detailed and balanced account of the Assizes. La Monte’s work is the most comprehensive and the most authoritative, and it has helped to refine our understanding of the Assizes’ significance. Other important works include those by Joshua Prawer, who has written on the Kingdom’s legal and political institutions, and by Jonathan Riley-Smith, who has written on the Kingdom’s history.
The Assizes and the Modern World
The Assizes of Jerusalem have been the subject of intense modern interest, both as a historical document and as a source of legal inspiration. The Assizes have been studied by legal historians around the world, and they have been the basis of numerous academic works. The Assizes have also been the subject of several modern editions, including the critical edition by Beugnot and the modern edition by Myriam Greilsammer.
The Assizes have also been influential in the development of modern legal thought. The Assizes’ combination of feudal law, commercial law, and religious law has been a model for various modern legal systems, especially in the area of multicultural societies. The Assizes’ treatment of the non-Latin population of the Kingdom has also been studied as a model for the legal treatment of minorities in modern societies.
The most important modern work on the Assizes’ influence is the collection of essays edited by Iris Shagrir, Crusader and Crusader Law (1997), which includes several important essays on the Assizes’ significance. The book has been the most influential modern treatment of the subject, and it has helped to refine our understanding of the Assizes’ place in the history of European law.
