Definition
The Royal Horse Guards were a cavalry regiment of the British Army that formed part of the sovereign's personal bodyguard. Known informally as "The Blues" (from their distinctive blue uniforms), the regiment was one of the Household Cavalry units responsible for the ceremonial and protective functions closest to the Crown. In legal and administrative contexts, the regiment held a defined constitutional role as a component of the monarch's bodyguard, giving it a formal status distinct from ordinary line cavalry regiments.
Why It Matters in Research
This term appears in legal dictionaries primarily because the Household Cavalry—including the Royal Horse Guards—occupied a specific legal and constitutional position in English law. Their status as bodyguard troops carried implications for questions of military discipline, Crown authority, command hierarchy, and the legal immunities or duties attaching to royal service. Researchers encountering this term in historical documents, parliamentary debates, army regulations, or property records (particularly those involving Horse Guards Parade and the Horse Guards building in Whitehall) should distinguish between three related but distinct referents: the regiment itself, the building that served as British Army headquarters, and the administrative office of the Commander-in-Chief associated with that building.
The term is most likely to appear in legal research contexts involving:
- Military law and courts-martial jurisdiction, where the regiment's royal bodyguard status could bear on procedure and authority
- Constitutional documents concerning the sovereign's prerogative over the armed forces
- Property and land records connected to the Horse Guards complex in Whitehall
- Parliamentary records concerning army estimates, establishment sizes, and regimental governance
Researchers should be aware that the regiment's formal history underwent significant change in 1969, when the Royal Horse Guards were amalgamated with the 1st King's Dragoon Guards to form the Blues and Royals. Any source after 1969 using the term "Royal Horse Guards" as a present-tense designation is either using archaic language or referring to historical context.
Historical Dictionary Support
Bouvier's Law Dictionary defines the Royal Horse Guards concisely as "a part of the King's body-guard" and cross-references the entry for HORSE GUARDS. This minimalist treatment reflects the dictionary's approach to terms that are more institutional than doctrinal—Bouvier acknowledges the legal relevance of the regiment's bodyguard status without elaborating on the constitutional framework. The entry's cross-reference to HORSE GUARDS is the more substantive one, as that entry encompasses the broader institutional apparatus, including the Whitehall headquarters that served as the administrative center of the British Army for much of the eighteenth and nineteenth centuries.
Historical legal dictionaries generally treat the Royal Horse Guards as a term requiring identification rather than analysis—their role is to locate the regiment within the constitutional order (bodyguard to the sovereign) rather than to parse legal doctrine arising from that role. Researchers should not expect historical legal dictionaries to capture the regiment's full administrative or military legal significance; for that, recourse to military law treatises, Army regulations, and parliamentary materials is necessary.
Jurisdictional Note
This term is specific to English and British law and has no counterpart in American, Scottish (distinct from English), or other common law jurisdictions. It appears in legal sources almost exclusively in the context of English constitutional and military law.
