Definition
The Breviarium Alaricianum (also called the Lex Romana Visigothorum, or the Breviary of Alaric) is a codification of Roman law compiled under the authority of Alaric II, king of the Visigoths, and promulgated in 506 A.D. for use by the Roman subjects living within the Visigothic kingdom in what is now southern France and the Iberian Peninsula. It is not original legislation but rather a selective digest of existing Roman legal materials — statutes, imperial rescripts, and juristic writings — adapted and simplified for practical administration in a post-imperial Western context.
The Breviarium drew from several sources, including portions of the Codex Theodosianus (438 A.D.), novels (novellae constitutiones) issued after Theodosius II, excerpts from the Institutes of Gaius, a condensed version of the Sentences of Paulus, and a fragment attributed to Papinian. Each excerpt was accompanied by an interpretatio — an explanatory gloss intended to make the classical Roman text intelligible to a less legally sophisticated audience. These interpretationes are in many respects as historically significant as the texts they accompany, offering a window into how Roman law was understood and applied in the early medieval West.
The Breviarium remained the dominant source of Roman law in much of Western Europe for several centuries, serving as the principal conduit through which Roman legal principles reached Frankish, Burgundian, and later medieval jurisdictions before the rediscovery of Justinian's Corpus Juris Civilis in the eleventh and twelfth centuries.
Common Confusion
The Breviarium Alaricianum is frequently confused with two related but distinct documents: (1) the Visigothic Code (Liber Iudiciorum), later Visigothic legislation of broader application, and (2) the Codex Theodosianus itself, from which the Breviarium drew heavily. The Breviarium is a derivative compilation, not an independent code, and not all provisions of the Codex Theodosianus appear in it — the selection and the interpretationes are the Breviarium's distinguishing features.
Why It Matters in Research
Researchers working in early medieval legal history, the history of Roman law, or the comparative development of European legal systems will encounter the Breviarium Alaricianum as a foundational source document. Several research traps are worth flagging:
First, terminology confusion: the term appears under multiple names in historical sources. Rapalje & Lawrence list it as Breviarium Alaricianum, but older continental scholarship frequently uses Lex Romana Visigothorum. English legal historians sometimes refer simply to the Breviary of Alaric. When searching catalogue records, manuscript indices, or older treatises, all three labels should be used.
Second, the Breviarium is not the same as the Visigothic Code (Liber Iudiciorum or Forum Iudicum), which was later Visigothic legislation governing both Roman and Germanic subjects. The Breviarium applied specifically to the Roman population under Visigothic rule; the two codes operated on the personal law principle common to barbarian kingdoms, under which legal identity tracked ethnic or subject-group membership rather than territory.
Third, researchers using the interpretationes must treat them as secondary interpretive glosses, not as direct statements of classical Roman law. They reflect Vulgar Roman Law — the simplified, customary adaptation of classical principles that developed in the provinces — and can diverge substantially from the juristic originals.
Fourth, the Breviarium's significance shifts depending on the chronological period under study. Before the twelfth-century rediscovery of the Digest, it was the Roman law. After that point, it recedes in importance as Justinianic texts became authoritative. A source citing "Roman law" without qualification in a Carolingian or early Merovingian context almost certainly means the Breviarium, not the Corpus Juris Civilis.
Historical Dictionary Support
Rapalje & Lawrence give a brief but accurate identification of the Breviarium Alaricianum, describing it as a compilation of Roman law made by order of Alaric II for the use of his Roman subjects and noting its promulgation in 506 A.D. The entry correctly identifies the Codex Theodosianus as the primary source material.
What the historical dictionaries understandably do not address — given their focus on Anglo-American practice — is the interpretive apparatus accompanying the text or the Breviarium's extended influence on medieval Continental law. Legal historians including Paul Vinogradoff and, more comprehensively, Ralph Turner and the broader Savigny school have documented how heavily the early medieval West depended on the Breviarium as a proxy for the entire Roman legal tradition. The entry in Rapalje & Lawrence is useful as a locator but should be treated as a starting point only; it does not capture the document's structural composition or its historiographical significance.
Jurisdictional Note
The Breviarium Alaricianum has no operative jurisdictional force in any modern legal system. Its significance is entirely historical. Researchers in Spanish, French, and Portuguese legal history will encounter it as a formative influence on the development of those legal traditions; researchers in Anglo-American law will encounter it primarily in comparative and historical legal scholarship.
