Definition
Mixed tithes are a category of ecclesiastical tithe arising not directly from the ground itself, but from animals and other living things that are sustained and nourished by the ground. Classic examples include wool, milk, eggs, calves, colts, and chickens — products that depend on the land indirectly, through the feed and pasture it provides. The tithe was assessed as a tenth part of these animal products, owed historically to the church or, after the English Reformation, to whoever held the right to receive tithes in a given parish.
Mixed tithes occupy the middle ground in the traditional threefold classification of tithes. They are distinguished from predial tithes, which arise directly and immediately from the land (grain, hay, timber), and from personal tithes, which arise from the labor and industry of individuals. Mixed tithes are so named because they partake of both the predial and personal character: the animals are sustained by the ground, but human care and labor are also involved in their keeping and increase.
Common Confusion
The three categories of tithes — predial, mixed, and personal — are frequently collapsed or conflated in general historical writing. The distinction matters for legal research because the rules governing enforceability, exemption, modusses (customary substitutions), and prescriptive rights could differ depending on which category applied. A researcher encountering a tithe dispute in ecclesiastical court records should identify which category is at issue before attempting to apply any general rule about tithes.
Recognized Forms
/SUBTYPES
Mixed tithes historically included:
- Wool and lamb (the most commonly litigated)
- Milk and dairy products
- Eggs
- Young animals (calves, colts, piglets, kids)
The exact items classified as mixed rather than predial or personal could vary by local custom and by the specific holdings of ecclesiastical courts over time.
Why It Matters in Research
Mixed tithes appear almost exclusively in English ecclesiastical law sources and in the records of the English church courts, particularly the Court of Arches and diocesan consistory courts, where tithe disputes were routinely litigated from the medieval period through the nineteenth century. American researchers will rarely encounter the term in a live legal context, as tithes of this kind never took hold in American law, but the concept surfaces in:
— Colonial-era property disputes in territories with Spanish or French ecclesiastical influence
— Historical research into the English common law background of property and agricultural law
— Ecclesiastical law scholarship and church history sources within the Law Mind corpus
A key research trap: the Tithe Commutation Act 1836 (England) effectively converted most tithes, including mixed tithes, into rent-charges, ending the practical distinction among predial, mixed, and personal categories for most purposes. Sources written after 1836 may use the older vocabulary in a purely historical or taxonomic sense, not as a description of live legal obligations. Researchers should be alert to whether a source predates or postdates commutation.
Burrill's entry introduces a slight variation in framing — describing mixed tithes as "natural products, but nurtured and preserved in part by the care of man" — which points toward why the category was contested: the human-labor element made personal tithe exemptions potentially applicable, and litigants regularly argued that a given product belonged in a more favorable category.
Historical Dictionary Support
Black's and Bouvier's reproduce nearly identical definitions, both tracing to Burn's Ecclesiastical Law and Blackstone's Commentaries. The core formulation — things "not immediately from the ground, but from those things which are nourished by the ground" — is Blackstone's language (2 Bl. Comm. 24) and became the standard shorthand in legal dictionaries throughout the nineteenth century.
Burrill's diverges meaningfully by emphasizing the human-care element ("nurtured and preserved in part by the care of man"), which more honestly captures why the category was legally interesting and disputed. The Blackstone/Burn formulation focuses on the indirect relation to land; Burrill's formulation highlights the mixed character in a deeper sense, gesturing at the labor question.
None of the three dictionaries address the post-1836 landscape or the practical obsolescence of the category following tithe commutation. Researchers should not assume that these dictionary entries reflect the state of English law at any given point after that reform.
Jurisdictional Note
Mixed tithes as an operative legal category are a feature of English ecclesiastical law. They have no direct analog in American law. Researchers working in jurisdictions with a Spanish or Catholic ecclesiastical heritage (Louisiana, parts of the Southwest) may encounter tithe-related concepts, but these operated under distinct canonical and civil law frameworks and the English tripartite classification does not map cleanly onto them.
