Definition
A title of English nobility, the third in rank within the British peerage, sitting below a marquis and above a viscount. The earl is the oldest title in the English peerage system, predating the Norman Conquest and originating with the Saxons. Under the Saxon system, earls exercised significant administrative authority over shires — a function from which the title "sheriff" (shire-reeve) later derived, as the earl's deputy assumed local governance. William the Conqueror made the title hereditary and granted it in fee to his nobles. Despite the title being male in name, the wife or widow of an earl holds the corresponding title of countess — reflecting the French and continental usage from which the equivalent rank (comte) was drawn.
In strictly legal terms, the significance of the earldom lies less in its social prestige than in its historical connection to legal privileges, duties, and the administration of English counties. The legal corpus treats "earl" primarily as a term of constitutional and historical interest rather than as an operative legal concept in modern practice.
Common Language
Modern common usage (Wiktionary): "The title of an earl."
Historical common usage (Webster's 1913): "A nobleman of England ranking below a marquis, and above a viscount. The rank of an earl corresponds to that of a count (comte) in France, and graf in Germany. Hence the wife of an earl is still called countess."
The ordinary meaning and the legal meaning are not deeply divergent here, but legal usage adds one dimension the common definitions omit: the historical administrative and jurisdictional functions of the earl, particularly the governance of shires and the earl's relationship to the shrievalty. Common usage treats "earl" as purely honorific; legal history treats it as once carrying real governmental authority.
Why It Matters in Research
Researchers encountering "earl" in historical English legal materials need to track two distinct phases: the pre-Norman period, in which earls held substantive administrative power over shires (and were sometimes called "shiremen" in consequence), and the post-Conquest period, in which that authority was systematized under the crown and the title became primarily hereditary and dignitary. Conflating these phases produces errors in interpreting the scope of authority in early common law sources.
The connection between "earl" and "county" is a live navigational issue. English counties (shires) derive their alternative name "county" directly from the French "comte" — the continental equivalent of earl. When reading medieval and early modern legal materials about county courts, county governance, or the shrievalty, awareness of this etymology clarifies why those institutions were structured as they were.
Researchers should also note that Anderson's Dictionary directs readers entirely to "SHERIFF" — a pointed editorial choice that underscores how thoroughly the administrative function of the earldom was transferred to that office over time. Following that cross-reference is often more productive than pursuing "earl" directly in legal sources.
For peerage law specifically (questions of inheritance of titles, rights of peers in Parliament, privilege of peerage in criminal proceedings), "earl" appears embedded in broader treatments of the peerage system rather than in standalone analysis. Searches should be structured accordingly.
Historical Dictionary Support
The historical dictionaries agree on the rank hierarchy (below marquis, above viscount) and on the Saxon origin of the title. Bouvier adds the most legally useful detail, noting that earls were historically called comites because they were expected to attend and advise the king, and "shiremen" because each administered a shire — a connection most other dictionaries underweight. Black's (both editions) and Burrill each note that William the Conqueror made the title hereditary, which is the pivotal moment separating the functional Saxon earl from the hereditary Norman and later English model.
Burrill cites Blackstone's Commentaries (1 Bl. Com. 398) directly — a reference that holds up and remains the authoritative classical source for the peerage structure in English law. Rapalje & Lawrence is sparse, providing the Latin and Saxon equivalents (comes; eorl) with little elaboration. Anderson, as noted, simply redirects to "Sheriff," which is editorially significant.
None of the historical dictionaries engages with peerage law as a system in depth, and none addresses the procedural privileges of earls in legal proceedings (such as the historical right to be tried by the House of Lords). For those dimensions, Blackstone and later peerage law treatises are required.
Jurisdictional Note
The title of earl is a creature of English and now British law. It has no operative legal equivalent in United States law, and American courts encounter the concept only in historical, conflicts-of-law, or inheritance contexts involving foreign titles. Scotland historically used "earl" under its own peerage system, which was formally unified with the English peerage following the Acts of Union.
