Definition
A letter of recall is a formal diplomatic instrument issued by the head of state or government of one nation and addressed to the head of state or government of another nation, officially notifying the receiving state that a diplomatic minister, ambassador, or envoy previously accredited to that state has been recalled and will no longer serve in that capacity. It is the counterpart to the letter of credence, which introduced and accredited the minister in the first place. The letter of recall formally closes the diplomatic mission of the individual named and marks the official termination of that person's representative status in the receiving country.
The letter operates at the level of heads of state and is distinct from the internal administrative act of recalling an official. The diplomatic significance lies in its public, sovereign-to-sovereign character: it is the sending state's official notification that its representative's authority and accreditation have ended.

Common Language
Modern common usage (Wiktionary): Formal correspondence from one head of state notifying a second head of state that he or she is recalling their state's ambassador.
Historical common usage (Webster's 1913): No entry recorded for this compound term. "Recall" in Webster's 1913 carries the general sense of calling back or revoking, as in recalling a person from a post or revoking a decision.
The common usage and the legal-diplomatic usage are closely aligned here, which is notable. The gap that does exist is one of formality and legal consequence: in ordinary speech, "recall" can be casual or informal. In international law and diplomatic practice, the letter of recall is a prescribed, protocol-governed document with specific legal effects under the law of nations — it terminates the accreditation of the envoy, extinguishes their diplomatic immunity as representative of the sending state in that capacity, and formally signals the change to the receiving government. The document's legal weight is invisible in the everyday sense of the word.

Common Confusion
LETTER OF RECALL vs. LETTER OF CREDENCE: These are paired documents that bookend a diplomatic appointment. A letter of credence (or credential) is presented upon arrival and accredits the minister to the receiving head of state. The letter of recall formally ends that accreditation. Researchers encountering either term in historical documents should confirm which end of the appointment they are examining.
LETTER OF RECALL vs. LETTER OF REVOCATION: Some historical sources use "revocation" in contexts involving the termination of powers or commissions more broadly (including consular exequaturs and letters patent). A letter of recall is specific to the diplomatic envoy context. Do not conflate these when working in historical sources dealing with commercial agents, consuls, or domestic appointments.
DIPLOMATIC RECALL vs. PRODUCT RECALL: The word "recall" in modern legal research more often surfaces in products liability, regulatory, and consumer protection contexts. A researcher searching Law Mind or any legal database without narrowing to diplomatic or international law sources will encounter an overwhelming volume of product recall material. These bodies of law share no substantive connection.

Why It Matters in Research
This is a narrow term of international law and diplomatic protocol. Researchers will encounter it almost exclusively in one of three contexts: historical treatises on the law of nations, primary diplomatic correspondence and state papers, and international law digests.
The term has not evolved meaningfully in substance — its function in diplomatic practice has been stable for centuries. What shifts across historical sources is the level of formality in describing the sovereign actors involved: older sources refer to "the executive of one nation" in generic terms that may mean a monarch, a president, or another head of state depending on the period and polity. Researchers working with 18th or 19th century materials should not assume the term implies a republican or democratic governmental structure.
The letter of recall sits within a network of diplomatic instruments that historical dictionaries often treat in clusters. When researching this term, expect to encounter letters of credence, letters de cachet (a distinct instrument), full powers, commissions, and exequaturs nearby in both primary sources and reference works. Understanding the full suite of diplomatic correspondence instruments will prevent misreading the function of any single document in the chain.
Jurisdictional research notes: because this is an instrument of international law rather than domestic law, it does not vary by U.S. state jurisdiction. Variation exists across nations and historical periods in terms of the precise ceremonial requirements, but the core legal function is uniform in customary international law.
One trap for researchers: the letter of recall should not be confused with the domestic U.S. constitutional or statutory mechanisms by which a president may be removed or an appointment revoked. Those are entirely separate legal instruments and processes. Similarly, state-level recall of elected officials — a distinct creature of domestic constitutional law — shares only the word.

Historical Dictionary Support
The three source dictionaries — Black's, Rapalje & Lawrence, and Bouvier's — are in near-complete agreement, differing only at the level of phrasing. All three define the instrument as a document addressed by one nation's executive to another's, informing the latter that a minister has been recalled. Bouvier adds the word "written," which is accurate but unremarkable given the documentary nature of all such instruments. Rapalje & Lawrence track Black's almost verbatim, suggesting common sourcing or direct derivation.
What all three sources omit is worth flagging. They do not address the legal effects of the letter — specifically, when diplomatic immunity formally ends relative to delivery or presentation of the letter of recall, a question that became more precisely defined in the Vienna Convention on Diplomatic Relations (1961). Historical dictionary entries predate or ignore that codification. A researcher relying solely on these definitions will understand the instrument's purpose but will miss its procedural legal consequences in modern international law.
None of the three sources address what happens when a minister is expelled by the receiving state (persona non grata declaration) versus recalled voluntarily by the sending state. The letter of recall is most properly associated with the latter; forced expulsions follow a different diplomatic protocol. This distinction is absent from all three entries.

Jurisdictional Note
The letter of recall is an instrument of customary international law and, since 1961, is governed in large part by the Vienna Convention on Diplomatic Relations, to which the United States is a party. Domestic U.S. law does not regulate the form or content of letters of recall; they are an executive function handled through the State Department. Variation in practice exists between nations but does not affect the instrument's legal recognition in receiving states.
