Definition
A period during which normal governmental authority is suspended, absent, or in transition. The term refers most precisely to an interval between two reigns — the gap between a sovereign's death or removal and the accession or election of a successor — but extends more broadly to any period in which legitimate executive authority is interrupted or in abeyance. In constitutional and public law, interregnum describes not merely a vacancy in office but a structural gap in governmental continuity: the machinery of authority exists, but the seat of supreme power is temporarily unfilled or contested. The concept carries significance wherever succession is legally regulated, because the interregnum defines the moment at which old authority ends and new authority begins — and therefore which law governs acts taken in between.
Common Language
Modern common usage (Wiktionary): A period between the end of one monarch's reign and the accession of their successor; a break in continuity or gap; in ecclesiastical usage, the period between a minister's departure and a new installation; more loosely, any transitional period between administrations or leaders. Historical common usage (Webster's 1913): The time during which a throne is vacant between the death or abdication of a sovereign and the accession of his successor; any period during which the executive branch of a government is suspended or interrupted. The common and legal meanings overlap substantially here, but the legal meaning carries a sharper edge: it marks a precise interval with concrete consequences for the validity of governmental acts, succession rights, and the continuity of legal authority. In common speech, "interregnum" has drifted toward metaphor — a pause between any two eras of leadership. In legal and constitutional analysis, the term retains its structural precision: it identifies a specific legal condition, not merely a rhetorical gap.
Common Confusion
Interregnum is sometimes used loosely to mean any change of administration or transition between officeholders. That usage blurs the concept's legal core. An interregnum is not simply a transition — it is a vacancy or suspension of authority, a period in which the seat of power is genuinely unoccupied or in legal limbo. A smooth succession where authority transfers instantaneously (as in the common law maxim "the King never dies," meaning legal continuity is preserved by immediate succession) is the opposite of an interregnum: it is precisely the legal mechanism designed to prevent one. Researchers should also distinguish interregnum from regency. A regency fills the gap — a regent exercises authority during a sovereign's incapacity or minority, eliminating the interregnum rather than exemplifying it.
Why It Matters in Research
The primary research significance of interregnum lies in questions of governmental continuity and the validity of acts taken during gaps in authority. Historical legal materials — particularly those from monarchical systems — frequently turn on whether acts performed during an interregnum were valid: grants of land, judicial appointments, treaties, and legislative acts could all be challenged on the ground that no legitimate authority existed to perform them. In English legal history, the Interregnum of 1649–1660 (between the execution of Charles I and the Restoration of Charles II) generated lasting legal controversy about which statutes, judgments, and grants made during that period survived. Researchers working in early modern English legal sources will encounter direct treatment of this period and its aftermath. In American constitutional research, interregnum surfaces in narrower but important contexts: the gap between election and inauguration (historically longer before the Twentieth Amendment shortened it), succession crises, and separation of powers disputes about acting officers and recess appointments. The concept also appears in administrative law when an agency head's position is vacant and the validity of actions taken by acting officials is contested. Trap for researchers: historical sources use interregnum with varying degrees of precision. Older political theorists use it in a robust constitutional sense; later writers use it metaphorically. Verify which sense controls in the source you are reading before drawing legal conclusions.
Historical Dictionary Support
Black's Law Dictionary (both editions) gives a spare, consistent definition: "An interval between reigns. The period which elapses between the death of a sovereign and the election of another. The vacancy which occurs when there is no government." The two editions are identical on this point, reflecting the term's stability in formal legal usage. Rapalje & Lawrence's entry for interregnum in the provided source material appears to have been corrupted in reproduction — the text rendered is clearly from an entry on interpretation or construction, not interregnum. Researchers should treat the Rapalje & Lawrence entry as unavailable for this term and not rely on it. The historical dictionaries appropriately center the term on monarchical succession but stop short of exploring the legal consequences of the interregnum — the validity of acts, succession of obligations, or continuity of courts. For that analysis, researchers must look beyond the dictionary shelf to constitutional histories and treatises on public law. Webster's 1913 usefully extends the definition beyond monarchy to include any executive suspension — a broader framing that anticipates the term's application in republican and modern administrative contexts.
Jurisdictional Note
The term is most doctrinally developed in systems with formal succession law — British constitutional history being the primary source. In American law, interregnum appears most often in constitutional and administrative law scholarship rather than in black-letter doctrine. Civil law jurisdictions with codified succession rules for heads of state may use analogous concepts under different terminology.
