Definition
Rights of things is a foundational organizing concept in classical common law jurisprudence referring to the rights a person may acquire over external objects or property—that is, rights concerning things external to and unconnected with the person. The phrase functions less as an operative legal term and more as a structural category, dividing the whole of private law into two great branches: rights of persons (concerned with status, capacity, and personal relations) and rights of things (concerned with property, ownership, and dominion over external objects).
The concept derives its authority from William Blackstone's Commentaries on the Laws of England, where Books II and III are organized around this framework. In Blackstone's architecture, the law of real property, personal property, inheritance, contracts, and commercial transactions all fall under the umbrella of "rights of things" because each involves a person's legally cognizable claims over objects or assets in the external world. The phrase thus served as the organizing header for what modern lawyers would call property law and, to some extent, the law of obligations arising from property relations.
Common Confusion
Rights of things is sometimes loosely treated as synonymous with property rights or real rights. The distinction matters for research purposes. Property rights is a modern, practical term describing specific enforceable entitlements in particular assets. Real rights (from the civil law tradition, jura in re) describes rights that attach to a thing itself and are enforceable against the world. Rights of things is neither of these—it is a taxonomic category in the Blackstonian system of legal organization, not an operative doctrine. Conflating the three distorts research into historical treatises and obscures the structural logic of pre-twentieth-century legal texts.
Why It Matters in Research
Researchers encounter this term primarily as an organizational marker in historical legal materials, not as a living doctrine. Its significance is architectural: understanding that Blackstone divided all of private law into rights of persons and rights of things explains why certain topics appear where they do in eighteenth- and nineteenth-century treatises, digests, and commentaries. A researcher puzzled by why contract law, inheritance, and property law share a common header in early sources needs this term to make sense of that structure.
Several traps await the unwary. First, the term appears in the titles and section headings of legal encyclopedias, treatises, and digests from the colonial period through the late nineteenth century. Finding it in an index or table of contents does not mean the source addresses a specific doctrine—it signals a broad subject category encompassing dozens of distinct legal rules. Second, American treatise writers and code drafters adapted and sometimes abandoned the Blackstonian taxonomy without always announcing the departure. By the time of the Field Code and subsequent codification movements in the mid-nineteenth century, the rights of persons / rights of things binary was being quietly restructured into more functional categories. Researchers working across that transition period should be alert to terminological continuity masking conceptual change. Third, the civil law equivalent—jura rerum, as noted by Burrill—connects this concept to Roman law taxonomy. Sources drawing on both common law and civil law traditions (particularly Louisiana, Quebec, and comparative law materials) may use jura rerum and rights of things interchangeably or in deliberate contrast.
For corpus researchers in Law Mind, this term is most useful as a finding tool. When historical materials use it, they are signaling the property-and-obligations half of private law. Cross-referencing entries on PROPERTY, REAL PROPERTY, PERSONAL PROPERTY, and JURA IN RE will fill in the substantive doctrine that rights of things organizes but does not itself supply.
Historical Dictionary Support
The four shelf sources are in close agreement, which itself is informative. All four trace the concept directly to 1 Blackstone's Commentaries 122, and all four offer nearly identical definitions: rights acquirable over external objects or things unconnected with the person. Burrill adds the Latin equivalent, jura rerum, which Black's and Bouvier's omit—a useful addition for researchers working in civil law or comparative materials.
What the historical dictionaries do not address is how this taxonomic category functioned in practice or how it was being displaced by the time these dictionaries were written. Black's first edition and Bouvier's were products of the late nineteenth century, by which point the Blackstonian framework was already giving way to more functional legal categories driven by codification and the rise of academic legal science. The dictionaries preserve the term as a historical artifact without noting this transition, which can mislead researchers into treating it as more doctrinally live than it was at the time of publication.
The second edition entry in Black's for this term appears to have a textual error in the source material as provided—the definition supplied is for RIGHT OF WAY, not RIGHTS OF THINGS. This kind of error in historical dictionary sources is a known hazard in archival and digitized legal reference materials. Researchers should verify definitions against original print editions when inconsistencies appear.
Jurisdictional Note
Rights of things as a conceptual category was most fully developed in English common law jurisdictions following Blackstone. Civil law jurisdictions (including Louisiana and Quebec) used the parallel Roman law taxonomy, jura rerum, but the underlying subject matter substantially overlapped. The term has no operative legal significance in modern American statutory or case law across any jurisdiction.
