Legal Definitions - Assizes de Jerusalem

The Assizes de Jerusalem refers to a comprehensive collection of legal principles and rules that were developed in the 12th century. Its primary purpose was to establish a coherent system of feudal law for the territories in the Middle East that had been conquered and were subsequently governed by European Crusaders, particularly after the capture of Jerusalem in 1099. Essentially, it served as the foundational legal code for the Crusader states, drawing heavily on the feudal traditions prevalent in medieval Europe.

Here are some examples illustrating the application of the Assizes de Jerusalem:

• Land Ownership and Feudal Obligations: Imagine a Frankish knight, having participated in the First Crusade, is granted a fief (a parcel of land) near the city of Acre. He then has vassals who owe him military service and rents. If a dispute arises between the knight and one of his vassals regarding the terms of their feudal contract or the inheritance of a sub-fief, the Assizes de Jerusalem would be consulted. This demonstrates how the Assizes provided the legal framework for the feudal system in the Crusader states, defining property rights, obligations between lords and vassals, and the mechanisms for resolving disputes within this hierarchy.

• Judicial Process and Criminal Law: Consider a scenario in the city of Jerusalem, after its conquest, where a merchant is accused of stealing goods from a market stall. The local authorities, operating under the Crusader administration, would refer to the Assizes de Jerusalem to determine the proper legal procedures for arresting the suspect, conducting a trial, hearing testimony, and imposing a suitable punishment, such as a fine or corporal penalty. This example illustrates the Assizes' role in establishing a system of criminal justice and judicial process for the new Crusader territories, outlining how legal cases were to be handled and justice administered.

• Governance and Royal Authority: Suppose the King of Jerusalem needed to levy taxes or raise an army for the defense of the kingdom against external threats. The Assizes de Jerusalem would contain provisions outlining the King's powers, the rights and duties of the High Court (composed of the kingdom's major lords), and the procedures for making important decisions that affected the entire realm. This shows how the Assizes served as a constitutional document of sorts, defining the structure of government, the distribution of power among the monarch and the nobility, and the administrative rules for governing the Crusader states.
