Definition
A compulsory levy of one-tenth of a person's annual income and the value of all movable property, imposed in England and France in 1188 to finance the Third Crusade against Saladin, Sultan of Egypt. The tax was directed by Pope Innocent III. and collected under the authority of Richard I. of England and Philip Augustus of France. The levy fell upon all persons who did not personally take up the crusader's cross — those who did enlist were exempt. Movable property used for personal wear or worship was excluded from the assessment base.
The Saladine Tenth is one of the earliest documented examples of a broad-based personal property and income tax in English legal history, notable for applying across both secular and ecclesiastical subjects and for its proportional structure rather than a fixed sum per head.
Why It Matters in Research
Researchers encounter the Saladine Tenth primarily in two contexts: medieval fiscal history and the early development of English taxation theory. Its significance in the Law Mind corpus lies in what it represents structurally, not just historically.
First, the Saladine Tenth is frequently cited as a precursor to later parliamentary taxation debates. When tracing the constitutional lineage of crown authority to tax — and the eventual shift of that authority toward Parliament — the Saladine Tenth appears as an early instance of a non-parliamentary, papally authorized levy imposed on English subjects. Its legacy feeds directly into arguments about who holds legitimate taxing power, a question that runs through Magna Carta, the Petition of Right, and ultimately the constitutional frameworks studied in modern legal history.
Second, the exemption mechanism — opt out of the tax by joining the crusade — is legally interesting in its own right. It is an early example of a conditional tax exemption tied to personal service, a structural device that recurs in various forms across centuries of tax law.
Third, researchers working in ecclesiastical law or the history of church-state relations will find the Saladine Tenth relevant as an exercise of papal fiscal authority over secular subjects in a secular jurisdiction. The tax was collected through both church and royal administration, making it a point of intersection between canon law and common law governance.
Trap for researchers: The date 1188 is consistent across sources, but some secondary literature conflates the Saladine Tenth with other medieval tenths and fifteenths levied in later centuries. Those later levies — particularly the parliamentary tenths and fifteenths of the thirteenth and fourteenth centuries — are distinct instruments with different constitutional foundations. Do not treat "tenth" as a generic synonym for the Saladine Tenth when reading medieval fiscal records.
Historical Dictionary Support
Black's Law Dictionary (1st and 2nd editions) and Rapalje & Lawrence are in close agreement on this term. All three sources identify 1188 as the date, name Innocent III. as the papal authority, and describe the exemption for enrolled crusaders. The 2nd edition of Black's provides the most complete surviving text among the dictionary sources, specifying the exclusion of wearing apparel and items of personal devotion from the movables assessed.
None of the historical dictionary sources engage with the broader constitutional significance of the levy or its relationship to the development of parliamentary taxation — their entries are descriptive rather than analytical. Researchers should treat these entries as definitional anchors and look to secondary historical and constitutional sources for interpretive depth.
The fragment appearing in the 1st edition of Black's under a general entry on salary-based labor theory is an artifact of page layout from the original printing and is not substantively connected to the Saladine Tenth definition that follows it in the source text.
Jurisdictional Note
The Saladine Tenth operated in both England and France under joint royal authority, but its legal legacy is primarily tracked through English constitutional history. It has no modern operational counterpart in any jurisdiction and is encountered today only in historical, legal-historical, and ecclesiastical law scholarship.

Researchers tracing the word "tenth" should note that the Tenth Amendment is a wholly unrelated instrument. No substantive connection exists between the Saladine Tenth and the reserved-powers doctrine of the U.S. Constitution.
