Definition
A paired Latin phrase from Roman law denoting two related but distinct forms of punitive banishment. The phrase is typically encountered in legal historical scholarship and comparative jurisprudence rather than in modern positive law.
1. Relegatio: A form of exile in which a person was banished from Rome or confined to a designated place or region, but retained Roman citizenship and the civil rights attached to it — including patria potestas (parental authority over family members), property rights, and the capacity to act in legal transactions.
2. Deportatio: The more severe form of banishment, involving permanent exile to a remote location combined with forfeiture of Roman citizenship. Because citizenship was the legal foundation for most civil capacities under Roman law, deportatio carried with it the loss of patria potestas, testamentary rights, and most other civil legal standing. It was, in practical effect, civil death accompanied by physical removal.
Together, the two terms represent the Roman law's graduated approach to banishment as a criminal sanction — exile with civil rights intact versus exile with civil annihilation.

Common Confusion
The two halves of the phrase are frequently collapsed into a single concept, particularly in English-language secondary sources that translate both as "banishment" or "exile" without distinguishing the consequences. The critical distinction is not geographic but civil: relegatio preserved legal personhood; deportatio extinguished it. A researcher who treats the terms as interchangeable will misread Roman legal texts that turn on whether a person retained the capacity to exercise property or family rights following punishment.

Why It Matters in Research
This phrase appears primarily in three research contexts: (1) Roman law scholarship and civilian legal history; (2) comparative treatments of punishment, civil death, and attainder in common law; and (3) historical dictionaries and treatises that use Roman law vocabulary to explain analogous common law concepts.
Researchers working in the Law Mind corpus should note that civil death — the common law doctrine that stripped convicted felons of civil legal capacity — is the closest functional analogue to deportatio. When 18th- and 19th-century common law writers invoked Roman banishment categories, they were often groping toward a framework for understanding transportation, attainder, and outlawry in their own tradition. Sources that reference deportatio in this comparative context may be making an argument about civil consequences, not merely physical punishment.
The phrase also appears as a unit in legal dictionaries, encyclopedias, and treatises on criminal law history, where it serves as a reference anchor for discussions of exile and transportation. Researchers should be alert to the single-source character of most English dictionary entries on this term: many entries, including those in 19th-century American and English reference works, trace to the same underlying synthesis of Roman sources and are not independent authorities.
Historical sources prior to the 20th century frequently omit the procedural and class dimensions of Roman banishment: deportatio was typically imposed on lower-status persons and non-citizens, while relegatio was more commonly applied to members of the Roman upper classes. This social stratification of punishment is absent from most dictionary entries and may matter to researchers working on the sociology of punishment or on comparative analysis of how legal systems calibrate sanction severity to social rank.

Historical Dictionary Support
Rapalje & Lawrence give a concise and accurate summary, attributing the substantive content to Brown (presumably Bouvier's Brown, or a similar civilian reference). Their entry correctly identifies deportatio as the more severe form and correctly identifies loss of citizenship — and the consequent loss of patria potestas and other civil rights — as the defining distinction. The relegatio entry is correspondingly accurate in noting that relegatio restricted but did not legally destroy the banished person.
What Rapalje & Lawrence do not address: the temporal dimension (deportatio was permanent; relegatio could be temporary), the procedural context (which magistrates or courts could impose each penalty), and the intermediate category of interdictio aquae et ignis — a still older form of exile that predates the classical deportatio/relegatio distinction. Researchers who need to work deeper into the Roman sources will find that dictionary entries at this level of generality are adequate for identification but insufficient for substantive analysis. The primary Roman legal texts — principally the Digest and the relevant titles of the Corpus Juris Civilis — must be consulted for doctrinal precision.
There is broad agreement across the standard legal dictionaries that the deportatio/relegatio distinction turns on civil consequences rather than on geographic severity alone. No significant divergence appears among English-language legal reference works on the core definition.

Jurisdictional Note
Purely Roman law in origin. Neither term survives as operative doctrine in any common law jurisdiction, though the concepts informed historical discussions of transportation, civil death, and attainder in English and American law. Civil law jurisdictions with Roman law foundations may carry derivative terminology, but the terms themselves are not current positive law anywhere in the modern world.
